Dreams What the What?

I don't know if this happens for anyone else but for me it's always around 3-5 days before I come down with something I begin having crazy and or bad dreams. Why is that? I know that people have fever dreams but why? With everything else going on when I'm sick it would be super nice if when I fall asleep my body and mind would get with the princess program and baby me. Dreaming is supposed to be your escape. Why do we even have bad dreams? Who dropped the ball and coded that into our genetics? What purpose can a bad dream have? Aside from maybe burning a few more calories or causing you to wake up having to pee. I mean I'm thankful to the maker and all but I thought I'd put in a small bug report. Imagine how much better the world would be if we all just had amazing dreams at night. I bet there would be a bunch more morning people. We would all wake up with a little extra skip in our steps. Instead I get the joy of either never remembering my dreams or having crazy dreams that don't make sense (like vacationing in Ireland and being able to just ride a 3 min ferry to JAPAN?????) I'm all for the confusing ones they add entertainment. I used to love when my little brothers friend would tell me what he dreamed because it was so random it was like so I was riding in a pickup with my dad and the McDonalds guy and we were laughing about this tv show and then the car tore in half but then we all went for Ice cream. I mean what the heck who wouldn't want to know a person who's subconscious throws that out at them? Like I'm a super random person. I asked my husband tonight while we were discussing my fever and what we should do for if I could bite his thumb. he said why? I said cause it's bigger then mine, I'd have to bite three of my thumbs to get the size of your's and I only have two thumbs. This kind of conversation is not even a little abnormal in my house (It's well established in my house that I'm a human vampire shark mix that really just wants to eat lettuce) but my dreams for the most part can be pretty boring. I have the occasional what the what? moment but for the most part I dream things that could happen you know if geography would cooperate. I think it's like an extra little peek into who someone is when you hear about a dream. I'm not sure what my re-accuring teenage dream of straightening +Justin Timberlake's hair says about me but that's for others to ponder at. I already know I'm nuts!
