I have read a book which suggest that maybe the 4th or the 5th dimension is the dreamtime, which is our dream. I guess all or most of us have this dream which seem to be going on like for many hours, but the fact that we have only been asleep for maybe half an hour.
There is this thinking or belief that maybe what is happening now, YES NOW, is a dream. The true "us" is actually the one in our dream. And the one which we are going to school, working, playing games and many other things, they are all our dream. The true us is in our "dream", however, we tend to always forget that we have dream about something, therefore it seems that we have spent most of the time in this dimension. ok, i know this might seems contradicting, even as i typed all this out, i got confused in the middle. WEll, this is just what i have read from a book years ago, just wanna share it.
