One of the possible signs of a fever is fever dreams. Researchers have shown that sleepers report their fever dreams to be strange, depressing, and emotionally intense in several studies Fever dreams are experienced differently by different people. People who are suffering from fevers may have no recollection of their dreams, while others may recall their fever dreams years after they first occurred.

What Is a Fever?

A fever is a sign of inflammation, and one of the body’s potential responses to infection or illness. Body temperature can vary widely among people, but 98.6 degrees Fahrenheit is considered a typical human body temperature (37 degrees Celsius). Flu-like symptoms are defined by the presence in adults of a temperature of at least 100.4 degrees Fahrenheit (38 degrees Celsius).

  • To combat an infection or illness, the body may produce a fever as an indication of inflammation. There is a large range in body temperature, although most people view 98.6 degrees Fahrenheit as a typical human body temp (37 degrees Celsius). In adults, a fever is defined as a body temperature of 100.4 degrees Fahrenheit (38 degrees Celsius) or above.
  • Extreme, teeth-chattering and shivering chills, known as rigors.
  • Weakness
  • Warmth
  • The feeling of being wet or hot.
  • Headache
  • Some respiratory symptoms include coughing or shortness of breath.
  • Dreams or visions associated with a fever

What Is a Fever Dream?

Sleepers who have a fever may have vivid, often odd, or downright unpleasant fever dreams. These dreams happen similarly to other dreams. The most vivid dreams occur during rapid eye movement (REM) sleep, though they can occur at any stage of sleep. Your dream recall is improved when you awaken during or immediately following REM sleep. Dreams can last anywhere from a few minutes to several hours, depending on the individual. Some people have black-and-white dreams, while others have vivid dreams.

Sleepers who have a fever may have vivid, often odd, or downright unpleasant fever dreams.

Dreams may also aid in the consolidation of memories and the processing of emotions. Research on 299 dreams found that half of them had at least one element that was based on a real-life event. As a result, heat and disease may be present in fever dreams.

When do they occur?

When your body temperature is greater than normal, you will have a fever dream.

The normal range for a human body temperature is between 97 and 99 degrees Fahrenheit. A fever is defined as a temperature of more than 2 degrees above normal.

Fever may occur as a result of your body’s reaction to:

  • an illness caused by a virus or bacterium
  • fatigue from overheating
  • Rheumatoid arthritis and other disorders that cause inflammation
  • antibiotics are one example of a medicine
  • an injection of a vaccine
  • a growth

What Fever Dreams Are Like?

It’s bad news because the vast majority of people who’ve had fever dreams describe them as disturbing. Your dreams may be more vivid and frightening when you’re having a fever dream than they are when you’re dreaming on your own. Sleep can be disrupted by these bizarre dreams, and it happens all the time. In addition, they have a few commonalities.

Heat or Fire

When a fever is present, it is common for the content of dreams to include images of forest fires, melting objects, and heat waves. Brain knowledge of the body’s rising temperature may be to blame.

Stressful or Intimidating Situations

Dreams that resembled childhood nightmares unexpectedly reappeared in adulthood for some people. As a result of their recent fever dreams, many people reported feeling threatened as well. Dreams of death, accidents, violence, or phobias may cause you to feel apprehensive. Negative feelings such as fear and grief are also common in dreams.

Fantastical Elements

Aliens, skewed sensory perception, and places that are significantly different from the real world are common themes in fever dreams.

Higher Dream Recall Value

Fever dreams also have a higher dream recall frequency than typical dreams, which means you remember them more frequently. Intense or unpleasant dreams may be a factor, as well as the fact that these dreams disrupt REM sleep more frequently. You’re more likely to remember a dream if your sleep is interrupted when you’re having it.

What Causes Fever Dreams?

The exact cause of fever dreams is unknown. Some researchers speculate that the “overheated” brain affects cognitive processing and therefore makes the fever dreams more strange than typical dreams. Fevers can also interrupt REM sleep, which may lead to other sleep changes, including unusual dreams.

How Are Fever Dreams Different From Other Dreams?

There is no recognized cause for fever dreams. The “overheated” brain, according to some studies, disrupts cognitive processing, which is why fever dreams are more bizarre than ordinary ones.1 REM sleep can be disrupted by fevers, which can lead to additional sleep disturbances, such as strange nightmares.

The following are some examples of fever dreams:

  • In one research of fever dreams, the most prevalent sort of dream was one with spatial distortion, which included moving walls, melting items, and changing the scale of spaces.
  • Dogs, insects, terrorists, and stones were just some of the things that frightened participants in the study.
  • In dreams, there are many different types of illness. In one study, participants reported having dreams in which they had symptoms of respiratory distress, discomfort, and dizziness.

Do Fever Dreams Have a Meaning?

It’s hard to say exactly what’s going on in someone’s fever dreams, but it’s possible that they’re connected to the person’s current situation. When a person has a feverish dream, they are more likely than not to have a health-related theme or temperature sensation.

Fever Dreams vs. Nightmares

The causes of nightmares and anxiety-induced fever dreams are different. If you’re having these disturbing nightmares, it’s possible that you have a sleeping issue like sleep apnea or narcolepsy. It doesn’t matter what causes them; nightmares can have a negative impact on your ability to get a good night’s rest.

Nightmares can be lessened by reducing stress and maintaining good sleep hygiene. Those with more serious mental health issues may need cognitive behavioral treatment. A sleep study can also reveal the presence or absence of a sleep disorder.

Fever Dreams vs. Lucid Dreams

Dreamers can become aware that they are asleep during lucid dreams. Some lucid dreamers are able to influence their dreams, as well. The lucidity of fever dreams was reported in roughly 40% of cases, according to one study. This is a much greater percentage than the 7.5 percent of healthy adults who have lucid dreams.

Are Fever Dreams Bad?

If you’re having a fever dream, it’s not necessarily a terrible thing for your health. Sleepers are unlikely to act out their dreams since most of them take place during REM sleep, when the muscles in the legs and arms are temporarily paralyzed. Sleepers, on the other hand, may have nightmares that are unpleasant or depressing. It’s possible that they’ll wake up feeling unsettled or uneasy.

Can You Prevent Fever Dreams?

However, treating the fever itself reduces the risk of having fever nightmares.

  • Prevent dehydration by drinking plenty of fluids.
  • Make sure you’re getting enough shut-eye. The benefits of sleep are numerous, including the fact that it aids in the healing process while you are sick.
  • Take ibuprofen or acetaminophen with the advice of your doctor.

Consult your doctor if your symptoms worsen or if you develop new ones while you’re sick with a fever.

FAQs

Is a fever dream the same as a lucid dream?

Honestly, no. Lucid dreams, on the other hand, are dreams in which you are aware that you are dreaming and that you are dreaming in the first place. It is possible to gain some control over the content and storyline of your dreams if you develop this level of self-consciousness. A fever dream is completely out of your control and you don’t even know it is a dream while it is happening.

Is it bad to sleep with a fever?

No. A fever is not the same as a concussion. In fact, if you’re ill, obtaining some shut-eye is critical to your recovery. A good night’s sleep not only improves your immune system but allows your body to focus on repairing itself rather than other activities like working, learning, or exercising.

Why are fever dreams so often nightmares?

No one knows the solution to this question. During the rapid eye movement (REM) stage of sleep, the body has a tougher time maintaining a stable internal temperature. When a person has a fever, the body’s temperature rises. Temperature has a significant impact on cognition, as well. Even so, it remains a puzzle that may never be answered, as to why all of this tends to lead almost exclusively to odd and unpleasant dreams rather than joyful ones.

Do other species experience fever dreams?

Despite the fact that other animals (such as dogs) are known to have dreams, little is known about whether or not their dreams are more intense during illness. The idea that animals can experience fever dreams while ill isn’t out of the question because animals’ dreams are similar to ours in both complexity and vividness.

Are fever dreams ever a sign of something serious?

As a normal cold can cause fever dreams, they aren’t a sign of serious illness on their own. However, if you have a chronic fever or illness, there may be a more serious issue at play. You should contact a doctor if you have moderate symptoms like a fever or a stuffy nose that last more than a week or two, according to the general guideline

Also, if you have a fever of more than 103 degrees, you should contact your physician straight soon. Remember that any temperature over 104 is a life-threatening emergency, as it can cause permanent brain damage.

What’s the difference between lucid dreams and fever dreams?

Lucid dreams and fever dreams are often compared since they are both vivid and easy to remember, but there is little in common between the two types of dreams.

  • A person is said to be lucid dreaming if they are fully aware that they are sleeping and in a dream. Aware people may sometimes control their dreams, and this helps to alleviate anxiety, control nightmares and enhance creativity.
  • Negative fever dreams, on the other hand, are something most people would rather avoid. They may feel helpless, anxious, or stressed out since they can’t influence what’s happening in their dreams.

What is the longest sleep stage?

NREM sleep, or sleep without rapid eye movement, accounts for about 75% of total sleep time. The four stages of non-rapid eye movement (NREM) sleep span from light sleep to deep sleep. Stage 2 (NREM2) is the longest stage of sleep, lasting anywhere from 30 to 60 minutes.

How long do fever dreams last?

The length of a fever dream is similar to that of a normal dream, and it is difficult to determine the exact duration. Dreams can last anywhere from a few seconds to up to 30 minutes.

Bottom Line

Thankfully, fever dreams aren’t usually harmful on their own, and they tend to fade away as your sickness progresses.

If you frequently suffer from unsettling fever dreams, the easiest approach to avoid them may be to avoid getting ill. If you’re unwell enough to start convulsing, Dr. Alicia Roth, D.B.S.M. explains, “the distress and discomfort of being ill may show up in your dreams”. Avoid touching your face as much as possible, wash your hands frequently, and don’t drink or eat after others. Both your mind and body will be grateful.
