Hahahaha...
I love reading what 'the man in the street' makes of these things...
Let me xplain about dimensions... and there really are lots of them, in fact if your maths require it, you can just pop up another to make it work!
They are a construct, a framework to give form to an idea, they exist only to perform this task!
'Pan-dimensional' merely means that something works when tested in some of the more complex constructs of Maths.
In this they are no different to the 4 dimensions we construct to make sense of the consious world we live in.
Think of it like this, to survive and go to work you need [say] just 4 coat hangers these keep your clothes smart and tidy, but if you go somewhere special you will need different clothes so you get some and you get some furhter coat hangers to keep the 'nice'... do you understand the analogy?
