I guess most of you have heard the saying - "Our thoughts shape our World" and this goes very well for the normal physical world as well as dreams.
But what if there were no thoughts? Wouldn't our reality then be created?
This idea came to me in a lucid dream when suddenly I seized to see the dream as pictures, but just thoughts. It felt sort of like a day-dream when the mind starts to create events and characters but you actually don't see them the way you see in the waking life...
"The Matrix" kind of shows the same thing - once You become aware that You're living in an illusion, You begin to see the System as numbers - in dreams, You begin to see the world as thoughts.
Just some thoughts.
