Another sleepless night...

OK so whoever said that teenagers need around 8 hours of sleep a day is a liar, because if I NEEDED 8 hours of sleep and was deprived of it enough, wouldn't eventually I end up getting 8 hours of sleep due to exhaustion?
If you were to ask my parents, I sleep too much. And if I don't sleep then its my fault for staying up on the internet all night... which is halfway true. It's amazing the time you can waste on facebook when you can't do anything else. However for the past 3 months I don't think I've fallen asleep before 3 o' clock once. I think ever since the second week of co op I've pulled an all nighter every single thursday, sometimes fridays... its not fun. Now my parents have decided that I have to be ready for school before 9:00. Not unreasonable. But then I have to get up around 8 to get my shower, get ready, eat, ect. So by defualt I get 5 hours of sleep at most. Well that's how it should be, but usually I don't wake up to my alarm clock, sleep till ten, and awake to my parents screaming that I need to learn responsibility.... great way to start the day.
On the off chance I do fall asleep early, I never stay asleep. I tend to have really bad dreams, very realistic dreams. Really bad things that have, or almost, or could happen like to replay themsleves when I'm asleep. Good memories not so much. I hate sleeping, I'd rather stay awake all night and drug myself with coffee in the morning. Of course I can't do that all the time... but I've learned that if I get myself tired enough- I don't usually dream. Or maybe I do, but I can't remember them. Hence never falling asleep till 3 or 4 in the morning. I think the most common phrase I use around my friends is "I'm tired." Because I really am! But I'm afraid to sleep, it's silly but I'm scared of nightmares, they stress me out. Also when I have bad dreams, I still feel tired when I wake up, so why sleep if I don't get the benefits of it?
Either way I need sleep, I'm getting grumpier and grumpier by the minute. But I think now that I've gotten used to this sleeping pattern its gonna take awhile to break it.
Tomorrow is the weekend though, and I'm spending the entire time with miranda and some friends when we go camping... I can sleep when I'm around friends, no bad dreams then. :)
