This is something that highly spiritual people have known for centuries.

Like, when you have an out of body experience, or you cast your mind into the sea of consciousness, you know that it isn't your mind that is thinking.

Our brains are made up of tons of tiny crystals. You could say, a crystal radio set. And this gets signals from a higher layer.

It is even more weird how this higher consciousness gets attached to a body, and feels that it IS the body.
