The nose RC is my best friend. I have a lot of false awakenings so I do a nose RC everytime I wake up. It helps.

The walking through a door thing sounds like a trip, I'll start doing that. I always ask myself if I'm dreaming when I'm in the shower or looking at the moon. Those are just two times that I'm usually reminded to do my RCs. I've been thinking about the post I saw from a guy who has a tatoo on his hand and everytime he sees it he RCs. It sounds good to me, but I can see where some other people wouldn't want to do it.
