What does the term fever dream mean?

According to Urban Dictionary, a fever dream is a slang term for some disjointed or strange experience. This experience may make you feel that you are in an actual dream where things outside the realm of reality happen. Many different things can be described as a fever dream, from an actual real life experience that makes someone feel odd and disturbed, to a piece of media, such as a television show or film, that has the same effect. Often, things can be described as a fever dream or acid trip when they are of this odd nature. 

What is the origin of the term fever dream?

According to Healthline and Time, the slang term fever dream comes from actual dreams that people have when they have a fever. A fever is when someone has a body temperature above its normal temperature. This can cause chills, cognitive processing, and insomnia, among other sleep disturbances. People usually try to treat fevers with medicines such as ibuprofen, plenty of rest, lots of fluids, acetaminophen or aspirin. When the internal temperature is high, this can cause body aches, weakness, headache, fatigue, hot flashes, or even strange dreams like a fever dream. A fever can be caused from many different things, from an infection from bacteria, to viruses. Different pathogens thrive when our body has a normal temperature, our body tries to heat up to make it more difficult for the temperature-sensitive pathogens to survive.  Other symptoms of a weakened immune system could include vertigo, or a sore throat. 

During rapid eye movement sleep, or REM sleep, the high body temperature disturbs the brain’s normal cognitive processes. This overheated brain can literally make your dreams bizarre. High brain temperatures can cause dreams of helplessness, menace, delirium, or other common fever dreams that happened during such ailment or malady. Make sure that the physical condition and core body temperature are treated, and this reduction in warning signs will reduce the dreams and intense feelings. These negative dream emotions can take a toll on a person. If they happen with too much frequency, see a doctor or a person who is qualified to do an interpretation of a dream. The doctor will treat the virus, and the dream interpreter may be able to give you a reason why you are dreaming of a huge dog, giant insects with oversized arms, or other odd dreams filled with creatures.
