Seeing as I've always wanting to have a lucid dream, I do an RC every hour or so. It's just become another thing to me. Sometimes I don't pinch my nose hard enough, and a little bit of air is released, so I have to try again. Recently I have stopped trying again, due to boredom.
In last nights dream, I did the RC (It's just a natural occurance, I can't help myself) and I could breathe through my nose FULLY with my nose pinched, yet I STILL wasn't convinced I was dreaming! I though "Oh... Ok.. Damn... Maybe next time I will be dreaming."
It's only until I woke up that I realised I was dreaming, then of which I kicked myself. Lucidity is impossible for me!
