Would it be possible for a different deminision to?

I think that by 'frequency' you mean a radio wave or an X ray or some other kind of penetrating radiation. In a kind-of way this is is not a bad analogy for something that, as you say, passes through you, without your being aware of it. But dimensions of space do not actually do that.

I find that a good way to think about extra spacial dimensions is to start by thinking clearly about the ones we already know about and experience in our daily lives, and then build on that.

For example - think of a 1-dimensional universe. This might be like ants living on a N-S railway rail. The ants can move as far as they like north or south, but cannot move off the rail, so anything to one side or another is unknown to them. A tree beside the line does not interpenetrate with the line - it is just not on it, so does not exist in the ant's universe.

Now allow the ants to live on a 2-dimensional plane. Suddenly all of the things to one side of the rail or the other are accessible to the ants, but their only experience of a tree is of the part of it that intersects with the plane on which the ants live. They are aware of it as something that they have to walk around, but they cannot climb it because they are limited to 2 dimensions. The branches, and the rest of the tree do not exist in their plane of existence. We superior 3-dimensional beings know about the branches, but to the ants they a pure fantasy. Note that if a higher-dimensional object intersects the ant's plane they will know about it, but only about a limited part of it. If a bird flies above them they will know nothing of it, but when it lands, its feet will suddenly appear out of no-where !

Now if we allow the ants to live in 3 dimensions they are able to climb the tree and explore all of the parts that we know about. They will be able to look up into the sky and see a flying bird.

And so it goes on - there might well be a 4th-dimensional part of the tree, or objects which exist entirely in higher dimensions without entering our space at all , but neither we nor the ants know anything about it or them because we cannot experience the 4th space dimension (if in fact it exists). The 4th space dimension, and any others you might like to speculate about, are so completely absent from our experience that we cannot even think about them in a realistic way. In this respect we are in exactly the same situation as the 1- or 2-d ants.

Another way of thinking about possible higher dimensions is to think of our experience of ordinary things as a 3-dimensional cross-section of a multidimensional object. This idea is clear in the case of the 2-dimensional ants - they experience the tree as its 2-d cross-section where the trunk enters the ground.

Before you get too enthusiastic about higher space dimensions consider this - the inverse square law of radiation implies that light and other electromagnetic radiation is confined to 3ds in just the same way that we are, and Boyle's law means that gasses are similarly restricted, since if we seal a container in 3 dimensions the gas will not leak out into the 4th when it is compressed.
