I've found a video that would be really cool if it were true, but I don't know how to judge its truth and it sounds ridiculous. This talk by Rob Bryanton deals with higher spatial dimensions, and suggests that different Everett branches are separated in the 5th dimension, universes with different physical laws are separated in the sixth dimension, etc. I can't find much info about the creator online, but one site accuses him of being a crank.Can somebody who knows something about physics tell me if there is any grain of truth to this possibility?

That reminds me of Tegmark's multi-level classification of multiverses, but that classification doesn't make sense as a spatial set of dimensions, IIRC.
