We all know the three regular spacial and the one temporal that we actually experience, but the 5th dimension contains possible worlds or alternate timelines. To use a spacial metaphor, if time goes forward (and maybe backwards) this would be the equivalent of going left and right through time. 6th is just a plane of all possible worlds with the same start conditions. Up and down. Presumably, this would allow travel to any of the timelines instantly and without needing to "manually walk" through progressively separate worlds, but I may be making that bit up.
7 would give us all different worlds with the same physics but different start conditions (more matter, less energy, less or more of both etc.). 8 is a plane of all this stuff, similar to 6, but "higher". Infinites apparently start appearing at this stage. 9 is possible worlds, with different start conditions and now accounting for different laws of physics. 10 is a plane of this infinite number of infinites and because we literally can't pretend to understand anything "above" this, it is for all intents and purposes the totality of reality. (and that's a phrase I never tire of saying.)
The important (and actually relevant) points of all this is that, firstly, these dimensions, one way or another, are sort of compacted into the same whole or are "connected" if you like. Secondly, and this is also a point to Snoop's 4th paragraph, its entirely possible that "all possible physical laws" could allow for blantantly (from our perspective) nonsensical or even contradictory physical laws and mutable physical laws that would, in turn, allow for the more chaotic dreams, assuming they are connected to these other worlds. An infinite number of possibilities would also account for the possibility of a species developing a sufficiently high technology level to actually travel amongst these dimensions. Maybe possibilities can interfere with themselves.
Of couse, all this could have resulted in a world (which we happen to live in) where dreams are a relatively mundane phenomenom, a world where dreams are mundane, but theres's enough false evidence to lead us to believe the opposite and a world where dreams are gateways or windows or whatever, but we would never know because there's nothing to suggest it.
At any rate, a study of this sort would probably be interesting regardless of where it leads, so, if anyone cares (and if I have any legal say in the matter to begin with) my journel is up for grabs.
