I'm not saying that it is impossible that more of these exist, but how would you propose a state of being that somehow managed to exist without utilizing one or many of these dimensions? I can't fathom a 2 dimensional creature, and there is no evidence of such a thing, and so I can't even imagine how there could be more spatial dimensions that we are somehow avoiding.
Like I said, your description sounds a lot more like parallel universes. Even though there is no evidence of them either, they would be a lot more plausible, and in fact would only require one more dimension for there to be an infinite number of them as you describe in your bed analogy. Like I said, string theory proposes up to 7 more dimensions that fold in such a way that they do not directly effect our spatial reality and could allow for this possibility.
