I also remember reading a story (maybe by Isaac Asimov – to be honest I can’t remember if it is his) where a child – very advanced works out how to loop time using something similar to a figure eight and mentally projects it so he can move through time and space.
It has also been said that we ‘dream out of time’. In Outer time there is a point where all is One. Every conceivable thing of life and experience at every level of the universe converges and is instantly present. People have dreams in a few minutes or even less that in a state of wakefulness could take several hours to experience. May be this can suggest why some people dream of events that happen in the future. They are out of time and therefor can move to the future. Sleep is the same state as deep meditation. The Alpha brain waves are similar in sleep as during deep altered states.
