I sleep like a baby - literally. I wake up every 2-3 hours on a good night. On a bad night, it's more like every hour, or sometimes every half hour. I usually fall back to sleep pretty quickly once I've been asleep already, but I never really seem to reach the deeper stages of sleep.
I'm also prone to anxiety dreams, many of which involve being lost somewhere, or trying to figure out something I'm struggling with. Sometimes, I'll find myself back in high school, and unable to find where I need to be, or trying to take some sort of important test that makes no sense. Often, I won't be able to remember any details when I wake up, just the sense of being lost, or struggling with something.
I can't remember the last time I had a full night of uninterrupted sleep. I suspect it's been quite a number of years. I also don't remember how it feels not to be tired.
