Trial and Error

I remember this from a few days ago. I think it was just a stress dream or something.

I am John Smith from "The Dead Zone" and I am within a totally black environment. I know that I have to touch something to get a vision that will guide me to where I need to be but there is nothing around, until suddenly there is a key ring of keys falling. I try to grab them, but they are out of reach. Then more and more keys begin to fall slowly all over, each incased in a light beam. I keep trying to grab them, but I can't grab any of them.
