I had this theory where sometimes dreams are what is really happening to me in another universe. I found this link.
So how would this dream theory work? How does dreaming hypothetically allow us to link into alternate dimensions? One idea is that since our conscious mind and the barriers it constructs are lowered, it allows our subconscious mind to cross over unfettered through these windows between realities, and suggests that at least our subconscious may be operating in our own reality and others simultaneously. The theory is that the full brunt of our subconscious mind is unleashed when we sleep, and that without our full waking consciousness turned on to lock us onto our actual reality we are perhaps more free to venture outward and make contact with the consciousness of our other selves. In essence we are able to more readily reach out into altered states of reality and consciousness.
