Yes - all the time.

I normally become aware im dreaming when my dreams get odd enough to tip me off that Im dreaming = a RC is just a finall confirmation.

I use light switches if one is close by - If they dont work or disintegrate then I know im dreaming.

My main RC is to fly - im an expert LD flyer - If Im pretty sure its a dream then I just focus on flying straight up - if I take off then Im dreaming.
