Infinitely close.....yet infinitely far away

                The multiple realities theory is something that I developed on my own based on a lot of science fiction and fantasy reading and my own beliefs. While it can't exactly be called a real, scientifically proven theory, I've spent a lot of time thinking through the different angles, and you will agree that it does make sense.
                 My theory stems from the idea of multiple dimensions that coexist with one another unwittingly, infinitely close, yet infinitely far away. The best explanation I've found of this theory is in Madeline L'Engle's novel A Wind in the Door, where the cherubim spreads his wings and then folds them and says, 'There. I have just brushed hundreds of other worlds with the tips of my wings and they don't know a thing.' Or something like that.
                 I believe that not only do these worlds exist, but that there are mental connections between them. I believe that when you 'create' a story, you don't actually pull it out of nowhere. You open a mental window to a reality just the next dimension over. Therefore, nothing is really imagined; it all exists out there somewhere.
                Now, you may ask, what if someone imagines a reality that doesn't yet exist? Well, the answer is a bit of a paradox, but try to think outside the lines to understand it. Before you imagine a reality, it doesn't exist; but after you imagine it, it did exist before when you hadn't yet imagined it. Think of it this way. When you imagine a reality, it is not just a brand new world, right? It's its own reality with a past and a history. SInce every reality moves along at the same relative speed, (although that's a bit difficult to measure as I will explain later), that reality existed not only after but before you created it. So there really is no reality that doesn't exist.
               What about the time frame? Well, as I mentioned before, each reality has a separate timeline that moves at the same pace as all the others. But within all the different realities, there are different sub-realities that are exactly identical, except that they are each at a separate point on their specific time line. You can see how this works using Future Trunks' time travels during the Cell saga.
        NOTE: If you are not familiar with the Dragon Ball Z story, please skip
         this next paragraph because you will be really confused!
               In Dragon Ball Z, Trunks travels from a reality (Trunks' reality) that closely resembles the reality that houses the entire Dragon Ball story (the DB reality). When he returns to the Trunks reality after visiting the DB reality, and then travels back to the DB realilty three years in its future, he actually does not return to the exact same reality. Within each reality, there are diifferent sub-realities that are identical except for their placement in time. So he actually returns to a different sub-reallity that is three years ahead on the DB reality's particular time line. This action is repeated in every sub-reality of Future Trunks' reality, each one returning to a different sub-reality of the main DB realilty. (Could I have used the word 'reality' any more times in that paragraph?)
               Memories also work on this sub-reality theory. When you remember an event from your past, you actually open a mental window to a sub-reality that is located at an earlier spot on our reality's time line. This also means that there are some true seers - they use this same process except that they look at a sub-reality that is located at a later spot on our time line. False seers do something similar, except that they see a seperate reality that is nonetheless very similar to ours.
               It's very hard for us to comprhend the number of realities out there. There is an infinite number, but it seems that there are almost more. Of course, this is only a theory that I made myself, not based on any scientific proof or carefully collected data. So you are free to believe it or disregard it as an unreal piece of confusion. But if you remember it, whether as a joke or as a well-written argument, you will never be able to classify the 'realism' of something in quite the same way.
