I slept very badly last night, waking up every hour or so, tossing in a sort of half-dozing state much of the time in between. I seemed to be dreaming the whole time. I had two iterations of my most common nightmare: falling. In these dreams, I always have some sort of momentum going (driving or riding in a car, sliding on ice, running, etc.) and suddenly realize that I'm not going to be able to slow down fast enough to avoid flying right off a cliff. My stomach always does this horrified drop and roll as I fly out into the air, knowing that I"m going to die, and every single time, at that point in the dream, I think, "I have to wake up before I hit the ground!" I don't know it's a dream the rest of the time, but as I fly out into nothing, I try to wake myself up.
