I keep hearing about how 'anything is possible' in lucid dreaming. I don't doubt that; there's no reason to. So a few days ago I was thinking and I suddenly wondered what it would be like to 'split' your awareness in a LD. Make a dream clone of yourself, and your subconscious takes in the sensory information from both parts.

Has anyone tried this, or anything similar before? I'd really like to know what this could result in, regardless of the placebo it would place on me...
