Been lucid dreaming for years. A few times a week actually, mainly due to my discussing dreams and altered states almost daily. Anyhow, had a thought the other day and found very little in the way of a Google search.

When one imagines something, they can visually place an object in front of their vision, and it appears as a floating, see-through object (much like a transparency sheet). Dreams, similarly, seem to have varying degrees of transparency depending on the vividness of the experience. Is it possible, then, that the dreams (as well as hallucinations and visual thoughts) exist as a tangible sheet of colors and patterns on the atomic level?
