So, this is why I love conversations like this- you think you're on a logic train of thought...and then something pops in your head- and changes it!
I read this earlier today and was like "OMG! This dude totally solved it and got it right!" To me, it does make sense that ghosts and other "unexplained" things are a rift or slowing of other dimensions...we're simply seeing something that's already there, but is beyond our capacity (right now) to see and understand.
I was thinking about this earlier this evening, because like you, I have had experiences which I can't explain. These have mostly been things moving, a whisper, or a movement/image out of the corner of my eye or a flash. Some would believe that these could be explained, but I truly believe that they are paranormal happenings. But I began thinking about my experiences, and I had one the night my grandmother passed away as well as a few months afterwards that I feel had to be my grandmother. I felt that what I saw, had an emotional connection to me. So this lead me to wonder if the us's in multiple dimensions are connected...could we share the same consciousness? Memories?
Well, as of right now...I don’t think we are really any closer to discovering the true nature of what one could call a “ghost” than they were 200 years ago.
But I think the big distinction between now and then is our understanding of the more subtle natures our universe hints at. Such as multiple universes, or matter duality, quantum entanglement, wormholes, etc..
On multiple universes...the theory is that there are an infinite number of universes, with an infinite number of you’s in them, in an infinite number of scenarios.
Now if you also take into account that matter can exist in two places at once...and in fact, scientists are looking at the human brain as a quantum computer for just such a reason....one theory is that our neurons are entangled on a quantum scale with one another, and that, along with electrical impulses is how our brains send information from neuron to neuron.
If you entangle two black holes, and then pull them apart, you have essentially created what is referred to as a “wormhole” which is a “shortcut” between them.
The scientific community has proposed that wormholes...mostly microscopic are constantly forming and vanishing all around us, indeed inside us too, at all times.
There is no scientific limit to how far away wormholes can go and still have information travel through it...so your mind could be entangled with the mind of someone else in another universe...it is scientifically feasible.
Who is to say that a schizophrenic isn’t truly hearing voices...at least in terms of them not being generated by his own mind?
We now see that there may be some ancestral memory encoded within our DNA...that these can account for our fears, likes, etc...perhaps it goes beyond that.
Perhaps, we are all entangled across time...and maybe across the earth? That could account for a global consciousness.
Perhaps you fear the ghost you can hear but not see because the other “you” you are entangled with in another universe is afraid of you as their ghost...and you are feeling their fear creating a cyclical fear?
This is such a hugely gigantic category of possibilities...lol...there really are infinite possibilities...lol.
