I think of the few things I've read of Erin's stated something along the lines of "if my conscious is not there, but it happens to my body in "real life", I don't really experience it. But a dream I take part in and remember it happening and experienced it, is just as real as if it hapened, and more real to me than what happened to my body that I didn't experience." Rough summery, but you get the point.
I felt that really hit home to me and made a lot of sense. Just one of the things is what happens if you forget everything? It's like you're not alive or something.
I'm just saying some food for thought.
