The first three dimensions are Width, height, depth.
The fourth dimension is time.
Thus the first three dimensions move through the fourth.
If you want to talk about the stuff of higher plains ... then you are talking about the 5th, 6th etc.
Do you have time to change your OP to get it right?

You do realize the concept of a 4th dimension is a dimension outside the boundaries of our perceptional limits right?

We have to distinguish between the metaphorical meaning of "the fourth dimension" as a general source of paranormal phenomena and its mathematical meaning. The latter is not helpful in explaining the former because supergravity theory and superstring theory predict that all the higher dimensions are compactified, so that they cannot generate large-scale, hidden universes that contain their own entities.
However, here is where the notion gets interesting: E8xE8' heterotic superstring theory is one of the five superstring theories that apply at different kinds of limits of the more general M-theory. As first shown by Witten & Horava, it predicts that two 10-d space-time sheets exist in 11-d space-time, separated by a narrow gap or segment extending along the tenth dimension of space required by M-theory/supergravity theory. The superstrings in one sheet are singlet states of E8' and the superstrings in the other sheet are singlet states of E8. This means that the two kinds of matter can interact with each other only gravitationally; they cannot cross the gap permanently separating the two universes. In the universe familiar to the five senses, matter is composed of E8'-singlet states confined to one space-time sheet; in the second sheet, matter is composed of E8-singlet superstrings and therefore it is invisible to any living thing composed of E8-singlet states of E8xE8' heterotic superstrings. It has only a gravitational effect on ordinary matter (it is an ingredient of dark matter). But suppose that entities inhabit this invisible universe and that human beings inhabit both universes simultaneously (after all, things in each space-time sheet occupy exactly the same 9-d space; they are merely separated by being confined to different points along the 10th dimension of space). Possibly, some of the creatures evolving in the hidden, parallel universe have developed the ability to materialise briefly in the other one, just as some people claim to have clairvoyant vision enabling them to see creatures unknown to science because they exist (most of the time) in the universe filled with E8-singlet superstrings, which, by definition, cannot interact with the physical matter from which scientific instruments of detection are made.
This intrusion (called "paranormal" by those ignorant of the wider, more complete nature of reality) would NOT be from a literal, "fourth dimension" - that's just a metaphorical way of speaking that tries to extrapolate the everyday, 3-d world to accommodate paranormal phenomena. Instead, the intrusion would be from an invisible universe that mirrors the familiar one in many respects except that it is displaced from it along a hidden, compactified dimension of space that renders the universe invisible to a science that has to rely on its physical means of observation/detection being built ultimately from E8'-singlet superstrings. Human beings, however, are not so restricted. They exist in BOTH universes simultaneously, although most (perhaps fortunately) have a brain-generated awareness of only one universe. But sometimes, when they have an OBE, they find themselves outside their physical bodies and able to roam about in the second universe in a body that always exists in it (but which they are not conscious of). This mirror universe looks in many respects like the one which they normally inhabit. The difference, of course, is that they can now pass through objects because their bodies are composed of only E8-singlet states of E8xE8' heterotic superstrings, which do not interact with the ordinary matter composing these objects except through the very weak gravitational force. You may ask: how can they see their inert bodies if they are viewing from the parallel universe - wouldn't their bodies be now invisible to them? No, because they carry with them the memory of their bodies and its environment at the time of the OBE, and all its information, stored in the subconscious, automatically generates a virtual reality of their former world that is superimposed on their new field of perception, which is sensitive only to what exists in the second universe filled with E8-singlet superstrings. This enables them to experience the physical universe, although they are no longer restricted by the laws of physics that operate there because they now function in the universe governed by different laws of physics, namely, those which apply to E8-singlet superstrings.
M-theory allows us the possibility of beginning to understand paranormal phenomena not in terms of fanciful higher dimensions of space but in terms of the two kinds of co-existing universes predicted by E8xE8' heterotic superstring theory, the theory that I suggest applies to the real universe.
