Imagine this sheet is lying horizontally so that if we were to view this plane from a bird's eye view, then we would see the sheet with its length and width.
However if we now view this sheet from another viewpoint so that our eyes are lined up horizontally like the sheet, we would then be unable to see the sheet because the sheet has no height.
Now similarly we have a 3d (spacial dimensions) Universe which we now take as the sheet. A 4d observer can see our Universe from a bird's eye view, but cannot see our Universe when he/she looks from a viewpoint horizontal to our 3d Universe he/she cannot see our Universe.
Seems logical ?
Now remember parallel Universes.
Lets say that we have a Universe with 4 spacial dimensions parrallel to us. A being on that Universe has a bird's eye view of our Universe and should therefore be able to see it !
