I almost dropped into a false awakening at my dojo.
They have a huge blowing fan, and we were doing corpse pose.
I kept imagining how much the fan sounded like the one in my room, then pictured myself in my room. i kept concentrating on that thought, and the image started to become vivider and vivider. I ALMOST woke up in MY BED in a false awakening, but my mind kept remembering the fact that i was in a dojo, not my room. so i kept getting a tingly feeling in my head, and finally we were told to get up and bow, so we could go. Either way i feel happy that i could've easily induced a false awakening right then and there if i hadn't anchored myself awake, (since we weren't supposed to fall asleep, just to relax) i could've triggered a MILD if i actually did wake up there :D
