I wonder, that since your eyes are closed while dreaming, can you blink your eyes while dreaming?

I'm going to incorporate this into my repertoire of RT's. I figured that it has 2 effects as an RT...1: Blinking might not be possible in the dream...and 2: Even if it was possible, holding my eyes closed and then opening them may change the scenery.

I especially want to ask the good lucid dreamers, have you tried this?
