I do not dream often.
Now, once all you neurology/psychology fags calm yourselves down again, I'll explain. I always, whilst growing up, encountered the verb "dream" in the context of a person experiencing an insane and inane landscape and sequence of events, and never in the context of a brain activity pattern. One believes that this is because the common definition of dream is so, rather than the brain activity associated with the mental phenomena.
When I sleep, I feel my consciousness fade away and then I return to consciousness with no perceived intervening period. Therefore I am not conscious and do not experience any dreams, hence I seldom dream.
When I do dream, it is generally in evocative concepts and convictions and rarely in a full environmental experience. The sequence of thoughts plays out in my mind, but no other experience occurs. Hence I do not dream in anime.
