Pretty much everything that tranquility trip has said comes straight out of einstein's theory of relativity. We experience time as he's talking about everyday like with the gps clocks. As well as all 4 of the dimensions that he has mentioned as they are all bound together. Im not sure how to link you to something supporting this but its not too difficult to find if you google the theory of relativity and time as the fourth dimension.

Hey doesnt it also say in his theory somewhere that if you could travel at the speed of light that time would stop for you or go backwards compared to others not moving at the speed of light?? This feels like its probably a dumb idea but maybe you could try using this idea somehow in a lucid dream...wait nevermind I guess this would only make it seem like time dilation would have happened. Nevertheless maybe a possible starting point perhaps?
