Finally had my first lucid last night *cheers!*
It was actually a really funny experience, I remember dreaming that I was in some sort of hallway thinking, hang on this isn't right. I slowly raise my right hand to my nose, plug it and try to breath - SUCCESS!
The funniest thing about it was me trying to keep calm and failing. I was telling myself the right things but it was clear I was excited; it was a bit like "OMG THIS A DREAM, OK CALM DOWN, CALM DOWN. OK STABALIZE, STABALIZE! KNEEL DOWN AND FEEL THE FLOOR, WALLS ETC!"
I woke up instantly and giggled to myself lol, it was really cool though.
