You really want to go here? I guess the sightings of what is classified as paranormal are that threatening to your hard-set conclusion of the non-existence of "spirit." A more interesting question is: If infrasound can be proven why not the subtle body or the astral body?
?? Infrasound is nothing but sound at a lower frequency than most people can detect with their ears. It is still often detectable in other ways, plus it is readily detected, recorded and produced by various pieces of equipment.
No one can even define a "subtle" or "astral" body, let alone detect one, and as far as producing such a thing, well, it just cannot ever be done.
When people claim they see a human ghost. That is a visual experience that is very specific. So just having a spooky feeling or seeing a smudge would not cover it. For similar reasons, well, UFOs, mediums, automatic writing, orbs, remote viewing, prophetic dreams, spitting up ectoplasm, fairy circles, psychokinesis, levitation, past life recovery, I could go on.
Rad Man, your question is kind of ambiguous. Do you mean “THE” explanation of paranormal, “AN” explanation of paranormal, or just a part of paranormal? It may be a tiny part, like a grain of sand on the beach. There are sound waves on many frequencies in the universe, but you know that. Some could be associated with the paranormal. Infrasound might be some of them, but it isn’t the paranormal or even a plausible explanation of paranormal.
I think it could be in some cases, but I definitely believe in the paranormal and metaphysics. My husband says I am quite an adept at sending things into a parallel dimension. Things I put away and we never see again. LOL
Here is something interesting about the human eye. When it's in motion (looking from thing to thing) we are blind. We also tend to move our eyes around the room when we are looking for things, which is the opposite of what we should be doing. It also explains why many claim to have not seen the other car they just hit when they looked.
Yesterday I finished our milestone and wanted to relax a bit. And then we randomly ended up having a discussion about Paranormal phenomena. My husband suggested me to watch Stigmata (which he has seen earlier). It was a...
