In high school my sleeping schedule was that of a stereotypical teenager - if I could (like in the summer), I'd be perfectly happy going to bed at 4 am and waking up at 1 pm every day. Coming to college I shifted more from 1 am to 10 pm, mainly because I had early classes and a summer job doing research, so no sleeping in. I've always needed at least 9 to 10 hours of sleep to be functional, I think because I just tend to sleep so horribly that I'm not getting restful sleep for a good chunk of the time.
However, I think I'm finally getting old. The past couple months I've found it physically impossible to sleep past 8:30 am, no matter how exhausted I am, when I went to bed, or if it's a weekend. I used to be able to sleep through blaring music, bright lights, and loud roommates, but now the second a ray of light slips through my blinds, I'm up. But the scary thing is that I actually feel well rested. Maybe I'm just finally starting to sleep through the night (a skill acquired by most as toddlers, but apparently not by me). I don't know what to do with myself this early in the morning. I mean, I don't even have breakfast food in my apartment - I usually just eat lunch first!
Oh well, as long as I don't get rid of my elaborate dreams, I'll be okay. Last night I dreamt that I took in two cute kittens as pets and named them Watson and Crick. I sooo wish that I could have a pet in my apartment. That will be a mental health requirement once I leave for grad school.
