Dreams

It strikes me to know that not everyone experiences dreams in the same fashion that I do. For example, identity in my dream-worlds is a very fluid thing. I am not always the person through which I am acting, even if I happen to be sitting across the room from myself, and I often have no identity at all in a dream except as a passive observer. Neither is any particular character the same person from one scene to the next. Occasionally people in my dreams lack any correspondence to their real life counterparts (appearance, personality, voice) but upon awakening I feel that they were a certain person, as if the writer of the dream intended for them to be but lacked the relevant information. Environments are equally as fluid and difficult to pin down.

I'm deeply curious as to what physical exchanges in my brain do I owe these strange characteristics and what differences in our waking lives and our development constitutes the differences in how people dream.
