As far as we know, there are no pockets or regions populated
by bulk antimatter.  Our universe seems to be all matter.
If there were anti-matter out there, it would eventually
(soon) bump into normal matter and there would be a massive
energy release.  We have not seen this.  There are experiments,
however, which are loking for trace amount of anti-atoms in
space, but it all seems to be matter.

That is a good question.  Certain progressive theories
suggest that there are indeed more dimensions.  String
theory is one such theory.  As yet, we believe that we
might see the effects of these other dimensions in particle
interactions, but we probably wouldn't be able to "step into"
those other dimensions or otherwise measure them.
