^^ This is why I do RCs whether there are people around or not! Just scratching my nose, nothing to see here (do nosepinch). You can also do glottal-stop (no hands) RCs, same thing, close off your throat with the muscles in your neck and you can't breathe.

And I think this one from last night for me is close to winning for this thread:

I'm flying/floating down a street, and I'm warping a spot of the ground/pavement with my mind into the shape of a perfect hemisphere about a meter in diameter which is floating along with me a few meters to my left and a bit ahead.

And I'm thinking: "It's too bad this isn't enough to get me lucid"!!!!!!!!!!!!!!!!!!!!! AAAAAAAAAUUUGHGH!!
