I've had a couple in my life, where I figured out I was dreaming. Detailed dreams like you talk about, where you keep falling back into them; I've done that a lot.

What gets me is when I have a dream and wake and then fall back asleep and start another dream where the first dream is talked about! My husband had one of those where he was looking for his car in a carpark and couldn't find it and got frustrated so woke himself and then realized he couldn't find it because he parked it in previous dream.

So, why did you force yourself awake? Usually I keep trying to stay :-) It's weird when you wake from one of those and just feel it was so real and expect the characters you actually know to think or behave now like they did in the dream, and to know about the dream.
