We dream alone

Dreams are a different place.

There are common dreams, and there are intensely personal dreams. There are helpless nightmares and ingenious lucid dreams.

I think the typical dream is a product of the imagination driven by the unconscious psychology, with enough remnant of the self hanging around to make the strange mental event "observable".

In a lucid dream much more of the self is present and is sometimes able to take control of the dream and guide it in chosen directions.

Common dreams of mine:

Flying

Buildings

Naked
