1. (figurative, descriptive) A disjointed or strange experience, especially one that engenders an even greater sense of outlandishness when considered retrospectively, similar to how actual fever dreams feel in real life.
2. (literal) A dream or nightmare, altered by a fever to become particularly confusing and bewildering at the time and even more so in remembering, like a Bad Trip.

Dream someone has when falling asleep, but wakes up repeatedly due to how sickening the dream feels. Usually mundane, repeated imagery that leaves one feeling frustrated and feverish because it just won't change.
Donny played lots of Smash Bros last night, but keeps having a fever dream of the campaign over and over again. He kind of wishes he didn't play for eight hours straight because it won't get out of his head.

A fever dream is a state of mental delirium experienced due to intense sickness. It is likened to a dream in that it is associated with a disconnect from reality and loss of coherence, understanding and awareness of your surroundings.

It is often used as an analogy for an unpleasant experience which seems too strange or traumatic to be real.
That party last night with those girls and the cocaine still has my head spinning, it was like one big fever dream.
That the house fire with all the screaming and crying was such a horrible experience, I'm still traumatised from it, it feels like a fever dream.

I was so sick drifting in and out of consciousness and delirious, i didn't know what was real and what wasn't, a literal fever dream.

An obviously rural attempt at an urban phenomenon. A gnar gnar rig. Something that would have looked normal in 1982, but not now.
