You don't travel "to" the fourth dimension. It's not like alabama or something.
One imagines space from the implications of having four perpendicular lines: that is, one stands on a three-dimensional floor, and looks at a wall where there are three perpendiclars.
trength and trong are just someone trying to spin you a yarn. If you're standing up (height) and facing forward (ie time is not the fourth dimension), then everything else is across: you have two width directions.
One must understand the model of the current universe is best explained in terms of a three-dimensional geometry, on which some kind of physics is built.
Well, one explores in the mind, a kind of universe where there are four or five or six perpendiculars, and builds the necessary bits and peices in the mind to play with. If you do it pretty well, and silly things don't happen then you get a fairly compelling image.
The biggest trap people make on 4D, is that it's somekind of over-three dimensions, and therefore must be really special (eg god lives there), or that the fourth dimension is somehow different to the other three (eg trength). It's not.
You can start to get an idea of 4d by looking at the 2D/3D hyperspace relation: you, as a 3D being, become a hyperbeing to a 2D thing, and so you set up a conversation between the 2D being, and yourself.
The idea is to try and replicate the model of the 2D being, because this is what it takes to see additional dimensions.
