The wise

say in my LD, i saw a wise person, a dream guide maybe, would what he tell me come from my own mind, or would it be coming form a source unknown?

(sorry for all the questions) :D

I don't think it can be said for sure. Your mind could possibly create a dream character as a method of bringing something foward into your consciouss from your unconscious. I think the mind is very powerful I have had some dreams recently where there have been very complex dream characters, but I think it is a way of my mind just helping me out.

I believe the dreamworld links to the spirit world.

In your dreams everything comes from your own mind. there is no external stimuli or information coming in that would add to your knowledge. Its amazing the things you remember when you have direct access to your subconscious :D
