Had a short lucid this morning.

I throw a knife at a wall. It spins in the air, then strikes the ground and bounces up and hits the wall lamely. I say to myself "I didn't believe it would happen so it didn't." This causes me to realize it's a dream. I walk over and pick up the knife, then look at my left hand to try to stabilize the dream. I'm holding it up in front of my face for about 2 seconds when I look down and the dream collapses.

How to I keep my eyes focused on my hands without feeling like I have to look away?
