Count my fingers, look at the clock and plug my nose (not in public )

I usually do them at random, or when I notice something weird, or potentially wierd.
I'm really lousy noticing any dream signs though. Everything seems so naturally, perfectly placed, in dreams, so it''s hard to ever question anything

The pen thing is a bit risky; say you dream that you look at your pen, but the dream plot steers you into not to be able to make the pen hover?
