I had this idea the other day while playing a first-person video game and doing a reality check with my hands directly in front of the monitor.

Perhaps a training technique might be to engage in a virtual world type simulation or game and whilst doing so, keep telling yourself its a dream as you navigate around and explore the virtual space.

The advantage, I'm thinking, is that you could but yourself in very bizarre environments where strange things are occurring, all the while telling yourself your dreaming. This awareness while in the virtual world my train the brain for the same experience in sleep.

I know some people claim immersing yourself in a virtual world during the day may impair lucidity, so I was curious to hear your thoughts...
