It's a completely different dimension when you realize you're dreaming, it instantly switches from bizarroland to a vivid as hell reality.

Last time I had one, I had just started realizing where I was right as I was waking up which ruined it.

It's pretty bazarre sometimes though, for example, I'd be in my old house in my mom's room, just staring out the window embrassing the moments i've had their, well at the same time believing I was there.. And suddenly i'm going out the window and there's a warehouse right next to it, and suddenly i'm in downtown, yet the house and whatever I saw out my window was still there, very bizarre feeling.
