Recently, I started getting into lucid dreaming, and for the last week I've been faithfully performing reality checks, including trying to breathe through a pinched nose, checking a watch, and trying to push my finger through my palm. My question is, how do you deal with performing a reality check in public? Some are more discreet than others, but sometimes it can look odd to pinch one's nose multiple times in an hour. (I usually cover it up by wiping my mouth, or pretending to sneeze). Any other ideas for doing an RC in a subtle way?
