I did this the other night, I'm a very novice lucid dreamer and can't seem to keep a stable dream going, and got lucid between dreams, I could tell my consciousness was in a very unstable state so I started to use a menu system like a box with the word 'menu' appeared, so I selected it and a new list came up of scenarios, I selected an option and further settings came up and as each item came up it rendered in the distance. I could feel everything destabilising, and a person I selected started blurring out into a mannequin and I started panicking that I was loosing it and then I lost it all.

Anyway, just wondered if anyone else has done this system before? Or uses it regularly..
