Yes, I would like to state that all that I have said here, is just pondering, purely theoretical, and purely hypothetical wondering, and should not be taken as fact, but, it is kinda fun sometimes to me, and those like me, I expect/suspect, to "do" sometimes, and it seems to broaden our horizon's and seems to kinda raise our level(s) of consciousness or awareness, even though none of it can be proven as, nor is meant to be taken as, "fact"... Kinda like science fiction or fantasy novels/stories/movies can...
Just keep in mind that it's all pure theory when you get on this kind of ground...
But, as far as the Bible teaches, their is at least two for sure, a physical reality and a spiritual reality that are tied together somehow, and are near to each other, but that's about all the Bible let's you know about it/them (other realities)... It does seem to suggest that those two realities can and do affect one another though... But, again, the Bible doesn't delve to deep into the intricacies of how that all works in great detail, cause were just supposed to believe (in) it by faith, I think...
God Bless!
