hmmm well i go through periodic bouts of dreams. for example, I will have several dreamless nights for up to a month at a time then for a few days to a few weeks I'll have vivid dreams nightly, sometimes two or three dreams in one night. Every once in a while, say once or twice a month, I'll have a nightmare. Now most of my dreams are wildly vivid and emotional, I can remember them very well and have continuations of them later on and even incite a desired dream before i fall asleep. most of my dreams are either extremely surreal or extremely realistic and involve me in the first person trying to run away from or catch something or some kind of goal. my nightmares almost always involve me running away from something.
