When I concentrated on myself...

Hi, I finally had a lucid dream after a pretty lengthy dry spell. It was pretty low level lucidity, but I had a significant amount of consciousness intact. I notice I was just roaming about the dreamscape with rather supernatural modes of transportation...and at some points, I figured I was dreaming. The moment I began questioning about where my real body is (on my bed at home) I began to lose focus of the dream, and it was fading away. I quickly abandoned focusing on my waking life and returned to the dream's events, and then I could maintain the dream state.

Has this happened with other people?
