Oddly enough, I don't dream. I haven't since I was a very small child. It's just dark for a few seconds, and then I wake up.
...is that weird?
When I did dream, though, most of it was nightmares. Usually about falling from high places or being separated from the ones I love. In order to wake up, I used to close my eyes tightly in the dream, and when I opened them, I'd be awake.
