This is all very “theoretical” so we don’t know for sure. One theory is that there are something like 20 small dimensions that we can’t see – but they’re not parallel, actually they are “perpendicular” which means at right angles to all the others.
Parallel universes are a completely separate idea – that there are other universes almost identical to ours, just slightly different and that they all exist in parallel. I think they only happen in science fiction and aren’t real!
