my sister used to see pink elephants hop across the room.
i sometimes do, though I rarely remember my dreams any day. but yes, when I have a fever (and I'm one of those people, I can get a fever up to 39° when I'm really sick, hands boiling, it's crazy) I get weird dreams. it's quite common, your sub-conscious is dealing with what happened during the day, but your perception is/was off because of the fever. and everything in your body and brain is running on such a high level because of your fever.
I'm never sick. Last time I had a fever was the first 2 weeks of third grade. But I remember it clearly. All I could dream of were a train at full speed coming at me, but never reaching me completely. And this little fuzzy buzzing light ball chasing me.
No, when I was a child, I used to have weird dreams when I am sick, especially when I had a high fever, I used to dream that I am laying on bed of nails and feel it like it is true and kind of feel more pain than the usual and wake up.
I had the swine flu, my fever was so high I don't remember anything from when it was over 105. But my parents said I had delusions that I was late for a concert, and I would point and laugh at things that weren't there
