that is a good answer, many times I did wonderful things in my dreams which in waking life I am not able to do, but that doens't satisfy my question, which I will take a little further now.
If we are not the body (I have an arm and who is the one who says that the arm in mine ?), and if we are not the mind (these are my thoughts and my emotions for example, so who am I, who possesses all of this ?), in that way the mind takes us to journeys outside the physical realms of existance (inside) to a place where it creates everything it want to transmit to us, right ?
I mean, an uninterpreteted dream is like an unopened letter fom God, many times the dream comes with a (hidden) message (for me).
So the mind consists of different entities which are capable of creating for us the dream (if we are not the mind, who is ?).
To take it a step further, we are soul, eternally blissful and not to be destroyed by any weapon whatsoever, and the soul is full of knowledge, only now covered by mind and body (matter).
The soul is desiring in nature, have you ever been knowing what you want to think, and when you think what you know, you already knew what you wanted to think ?
And then you think : "Damn, what a waist of energy, I already knew it!"
It happens in meditation, it's the soul who is desiring to think and it uses the mind to think, like we use a computer to expres ourselves.
Anyway, I am convinced that the mind creates the dream, somewhere else and there everything is possible, so even the girls in the dream I knew, but not in real life.
By the way, you're a hell of a guitar player, man !!!
