Immagine that somewhere in a galaxy far far away, our 3D spatial universe degenerates into a 4D spatial variety, bordered by 3D varieties, but keeping the rest of its properties - quantum physics would still work, matter would still exist, time still exists, only the space gets a new dimension.
If you want an analogy, think Flatland, but at some point the sheet of paper acquires a 3D "bulge". The flatlandians wouldn't be able to spot the bulge from far away in their 2D world, but when they cross over into 3D land they would start noticing - gradually - some very strange properties, change of perspective, etc.
You would ask, why 4, why not 6, 8, 12 or 100.000. Well, 4 is a good start to study such an oddity of our Universe, with the purpose of writing a modified OGL engine and bulding some Celestia sister-app which would render such a pocket in space.
Crossing into this pocket would not be a discrete event, but rather a continual experience - the edges of the bulge degenerate into 3D space gradually, hyper-volume limits to 0. 4D-People living inside the bulge would see its edges as an event horizon. 3D-People coming into the bulge would maintain their 3D structure, but experience physics as it would exist in a 4D world.
So if you aren't totally lost, write some impressions about "tesseracting" such a space, and about the possibilities of its existance.

Einstein would roll over in his grave. Not only does God play dice, but the dice are loaded. (Chairman Sheng-Ji Yang)
If there is such a thing as 4D space, it is infinite and everywhere, and we are in it right now. Also, if there is 4D space, then there is most likely 5D space, 6D space, and infinite-D space (which we would also be in right now).
The closest thing to what you're talking about is an area in space where (for whatever reason) the actions of higher-dimensional physics are somehow more apparent to us measly 3D beings.
Booyah!
