Just though I'd throw this out. Not sure if this is the right place to post.

It seems that oftentimes when I'm sleeping but still awake, I often can remember certain pictures of people within my mind. In fact, more accurately than I can in most parts of the day. I can pretty much picture them near-perfectly when I'm sleeping than when I'm awake. I've noticed this phenomena over the past few days, and thought I might as well ask.
