Okay, so me and my friends have noticed a pattern of dreams when we get sick. This is fairly confusing so I'm going to explain it the best I can. This all takes place while being sick with a fever.

-After sleeping for x amount of hours, I woke up for school, realize that I had a fever, told my parents I couldn't go to school, then went back to sleep.
-Upon going back to sleep, I slept for another 5-6 hours. During this sleeping time the longest, most vivid dreams me or any of my friends have ever experianced take place.

This is one fever dream I had about a year ago that I typed up when I woke up because I didnt want to forget it (you dont have to read this, its just an example of the length of the dreams):

"Alright, so it starts out with me at parsons house in his basement during a band practice. We're playing music, and we see something move outside the window, so we go to investigate. So now we're outside, and everythings fine, only parsons house is alot bigger and has this huge pool with this like rock sticking out about 20-25 feet about the pool with stairs going up to it. So I'm there talking to parsons, when some cats start circling around us. I try to fend them off with my guitar, but they keep getting close, and they chase me up to the rock thing. Eventually, I lose balance and fall the 20-25 foot drop into the pool. I become unconcious, and stay unconcious as my family loads me onto a plane for a ride across the ocean that had been planned for a while. The plane crashes, and when I finally awake from my unconiousness, im out of the plane, laying on sand, and I look up and my dad and alot of people i dont know are there. We all go into the woods and there are paths, so we all split up. Me and my dad went together into one path. We kept walking untill we reached another beach. from there we could see another piece of land with tons of people. This made us excited, but we wanted to check it out before we went back to the other people. so we swam across the like 100 miles to the other place, and when we get there, we are greeted by a man speaking in Italian. He tells us that we are in a small town in Italy, and gives us each a pair of mocasins. We dry off, and now we are standing on a bridge. A couple about to be wed walks by, and my dad dares me to walk past them and pretend to check the girl out as a joke. So i go over and do it, and the girls fiance stop and kicks me, so i fall to the ground, then kicks me some more. They walk away and i get up, laughing really hard. I then walk back to my dad and we enjoy some pasta at a pasta vendor (yes, a pasta vendor). Suddenly, down the street comes a reaaaaaally old car (the ones that are kinda shaped like boxes with the cranks in the front). Its coming straight towards me, when i realize that its the girl who was about to be wed, and she looked angryyy. So I try to run, but its hard to in the mocasins the man gave us. I start cutting through peoples yards, as the woman in the car yells that im violating trespassing laws. Soon there was a yard with a small 10 foot wide river in it, so i decide to ditch my mocasins and jump in the river. I keep swimming for a long time.

At this point, my dream switches perspectives, so now im not seeing what I see, but I'm seeing whats happening on the bridge up ahead of me. The river i was swimming in opens into a lake, and across the river was a big wooden bridge. A crowd gathered as the girl who was about to be wed stands in the middle of the bridge with a shotgun, explaining the laws that I have violated and what cause she has to shoot me. Meanwhile, I keep swimming towards her, not knowing any of this could happen. As she is about to shoot me, my dad pops out of no where and tackles the woman, and the shot is never made. I make it to the bridge and we explain about how our plane crashed and how all this happened, and the woman says something, and suddenly we are on the top level of an air port. I have my bike and my dad gets on the pegs (and suddenly my bike turns into a jetskii...wtf???) We ride down the stairs and take wicked sharp turns and hop from staircase to staircase, and when we reach the bottom, a black policeman with a moustache comes over and says "hey, kids should wear helmets" and i said sry and he let us get away. We stocked up on food to bring back to the people who were on the plane with us, when suddenly I reach into my pocket and realize that my iPod was broken from all of this swimming. "

So, my question in, has anyone else had experiances like this, or have an answer to why this happens, and feel free to discuss anything related to the topic here.
