I know I never have false awakenings. Any time I wake up, I'm in my bed at home and things are normal. I've never been in my own home because my own home in a dream is always some other place than IRL. Maybe I'm just wierd, though.

EDIT: Re-read your post....actually, that sounds kind of interesting. I always have that feeling of RL heaviness when I wake up temporarily...but I've to check.
