Have you seen a very serious or confusing nightmare when having a fever? These are called fever dreams.

In today’s post, we will know the science behind such dreams.

Fever dreams – what exactly are they

Fever dreams are nightmares that occur during fevers. Even if you are someone who does not dream often, and sees nightmares rarely, fever dreams might occur in your case too.

In a study conducted in 2013, people were questioned about their fever symptoms. Apart from the usual signs, the respondents also mentioned that they had experienced weird and intense dreams during fever, reports Time magazine. They went ahead and claimed that the dream involved repeated actions and movements. Some reported that the dream kept shifting between a pleasant one and a terrifying one.

In another study conducted in 2016, also reported by Time, participants agreed with each other on the nature of their fever dreams. They accepted that these dreams were negative and left them more restlessness when they woke up as they could remember everything in specific detail.

How are fever dreams different from usual dreams? The most important factor in differentiating the two is the emotional intensity of the dream. Fever dreams tend to be more emotional compared to regular dreams. They hover toward the negative side of the emotional dream spectrum. This is why you might wake up feeling even more drained and deluded after experiencing a fever dream.

Also, the other component that separates the fever dream from a regular nightmare is that in the former you are able to recall the dream in detail. Some of these dreams include feeling suffocated, walls caving in and crushing you, Kafkaesque creatures, etc. You might even wake up asking for help, certain that someone wants to harm you or kill. That is how realistic the dream might feel.

Seeing an unrealistic big dog that chases you to no avail, or being captured by terrorists etc. are also other examples of fever dreams. You could also see the same dream throughout your sleep.

Fever dreams are linked to feelings of fear, stress, and restlessness.

If you had a weird scary dream when going through a fever, then don’t worry. Turns out, you are just having a fever dream and they are not dangerous.
