I haven't had a fever in years but I'm getting over the flu and yesterday my fever was up to 101 degrees. I slept on and off all day and had these dreams I can't even describe. Half the time it was like I was not even asleep, I was just lying in my bed semi concious and had all these weird thoughts and dream-like ideas in my head, and I flowed in and out of sleep. Also, before I went to bed I was on the couch dozing off and I asked my boyfriend if he was going to take a nap before work and he said yes. Then I asked when he was going to take a nap and he said "in about 20 minutes". I said, "so you are going to bed in 20 minutes?" and he looked at me and said, "no, I didn't say that." I said "did I just dream that we had that conversation?" and he said I must have b/c I was sleeping and the first thing he heard me say was "so you are going to bed in 20 mins." It really seemed like the conversation happened though, and later I apparently *really* had a phone conversation with my mom and didn't remember it later. I guess I was delirious or something, and I know fevers can affect dreams.

Does anyone have more information on what physically happens to cause this when you are sick? Has anyone had similar experiences?
