Every since I was twelve years old, i've had dreams about things in my life. One recurring dream is, i am always at the house I grew up in, everything is the same except for one small detail, I am the only child. At first i thought nothing of the dream, but then month after month it would occur. In some episodes, i found out that key elements true in my waking world life was not the case in my dreamworld life.
Like the high school I went to is different, and certain friends i'd had were of another ethnicity in this dreamworld. It lingered in my mind as a mystery until a couple of years ago. I was watching a PBS special about physics, on it was a guy named michu koku (I believe i've spelled it wright), a professor at NYC college. He said that there were anywhere from eight to ten dimensions that they were aware of (personally I think it's somewhere like billions) existing in the universe. Each realm/dimension having its own rules and laws. After hearing this, coupled with the many dreams i've had which something from the dream manifested in the waking world, I theorize that sleep is a second awareness. Sort of like a radio station that is always there, but needs to be pointed to by frequency,(ie; thought, energy). The dreamworld is the "physical/mental " in this state of consciousness, just as this three-dimensional plane is in the waking world. In the dreamworld, seperation of time and space do not apply, and you are able to see many aspects of yourself(ie; multi-dimensional selves, past-life selves) and of reality.
From this knowledge, I summarized that my dream has to be an 'other-dimensional' aspect of myself, and I am simply "looking in" on his reality, as he probably does of mine. His world is smallishly different from mine, but the differences are very noticable. From my last dream I now know he is graduating from college soon, while I attended community college and has already graduated.
If most of this sounds unbelievable to you, I understand, but the next time the phone rings in your dream then you awake to find it ringing, ask yourself "how"?
