I think it depends on one's definition of the word "dimension." The word has myriad meanings for many people. It can have a highly specific, even
technical meaning for physicists and cosmologists. It can simply mean any modality or "way" for something to exist, move, or be to others. It can
mean for some simply an aspect of a thing or person. (i.e. something as simple as the addition of multiplayer in a videogame adding "another
dimension" to its gameplay.)
We believe we perceive a three dimensional, physical reality (whatever the nature, be it literal or illusory, or some combination thereof, of that
reality might be) moving and changing through a fourth dimension of time. (In a sense, time is simply movement, so one could say that purely
three dimensional space would entail no relative motion whatsoever, and that as soon as any is introduced, a fourth dimension is present.) We
suspect that there are other dimensions. In some theories the hypothesized fifth dimension would exist as all of what we regard as time - the
"past, present, and future," - simultaneously, existing as a solid whole.
Some other theories hypothesize that dimensions beyond our seemingly native four might be radically different - perhaps exceedingly minuscule, perhaps
not flat as we believe our four dimensional space-time manifold to be, or perhaps not even contiguous with our own manifold.
Others regard any "higher" dimensions to be spiritual, astral, ethereal, etc.
Some indeed believe that this is all there is, and that there are no additional dimensions.
Still others believe that the very concept of dimensions is a human concoction predicated upon how we perceive and interpret our reality.
So with all of that said, I think it would be more accurate to say that I suspect the existence of other dimensions, rather than to say I
believe in other dimensions. I cannot personally prove the existence of other dimensions in my opinion, so I don't know.
