My first LD? I don't know what triggered it exactly, but I was in a small grey building thing... and it kind of just hit me that I was dreaming. I kicked down a metal door that led to outside, and ran faster then humanly possible... so fast, I lost lucidity and transitioned to a different dream scene. I think sometime after I had my longest lucid on record which was about, 30 min? Yeah around that. Felt amazing, but unfortunanty I've been very on and off with lucid dreaming, because of life >_>.
