Partial tangent, I used to lucid dream a bit when younger. While doing so I felt that the imagery was a lot more colourful and fleshed out than when I would consciously daydream.<p>Translated to IT terms, I always thought that I had more computing power available while my conscious brain was partially disabled...or perhaps that my conscious brain had a limited information scope (ie. bandwidth) which made it filter out too much extraneous information, making me feel as if I (as a conscious entity) could only experience and be aware of less information at a time than in semi-conscious states.
