This is obviously just anecdotal, but when I was 6 I got very ill with the flu and was in bed for days. Super high fever and was quite out of it.
I had a, idk, spell one afternoon where I saw this quilt we had on the wall open up at all the squares, and thousands of tiny people/elves poured out. They marched around carrying little boxes and were all around me.
I remember it so vividly more than 30 years later because it freaked me out so much. Tried telling my parents about it and they just dismissed it as a nightmare, but I swear I was awake, just out of it with fever.
Anyways, it was early 90's, and I know I was close to the dangerous temperatures of high fever. Perhaps the brain does interesting hallucinations in these situations?
Have never hallucinated or had anything like that happen since.
likewise, the opening to Comfortably Numb always resonates.
You can get brain damage and seizures with a high fever and we knew that in the 90’s. We already had almost all of the fever controlling drugs we use today by the 90’s. What the hell was wrong with your parents? Do you still talk to them? That’s child abuse, buddy.
I've hallucinated with fevers before, and they do feel surprising that you swear you are awake, but perhaps you're really in a twilight between awake and asleep and the dreams break through.
I've had very, very bad dreams and hallucinations when I had fevers as a child. Never saw tiny people, but definitely had weird non-euclidean experiences, and my parents told me that I'd be laying there screaming about something that I had no memory of the next day.
