I would like to see my theory as being flexible and adjustable too but just from personal experience, it seems the more conscious I am, the more I can't do anything special. When I'm semi conscious, I often get triggered into a lucid dream in the middle of flying and my thought is always streamlined, e.g im only driven by a single thing I remembered from real life, like find a special book. but when fully conscious, I have access to a few goals from real life (also limited to a few things). Since there is no science behind it, it's hard to say this opinion is the fact.
One night, not long ago, I was on a drug so I slept early, woke around 530 or so and went back to bed, I laid around trying to sleep, while there I could partially feel my body going numb, then I think I slept off only to realize I was standing in my room. Then I realized I was dreaming/oob, I went to the door and the first thing on my mind was to walk through wall or the door, I couldnt, so I just opened the door and walked out to see someone I didnt know standing at the door. The whole lucid dream thing just happen anyhow, I cant really say anything solid about it.
