Hi Phi (couldn't resist;) ) You started off with...
“...no ghost existed in the real world. They exist in the imaginative world which was created by each one’s aggregate of imagination.
So, Phi, in your hypothesis, ghosts are not noumenal, and are only phenomenal in the sense one experiences them. In “reality” they are epiphenomena of “one’s aggregate of imagination”, by which I assume you are describing that part of our “psyche” Jung called the collective unconsciousness.
Have I got your range so far?
By my experience of this phenomena, “collective” is accurate, in the sense of that groups can experience what they agree was the same “ghost”, “ufo”, “mothman” etc. (my fav term, and theory, is “quantum flux”)
That said, Phi, why return them to normal life? Reminds me of old Freud saying the goal of psychoanalysis was to free one of neuroses so one could enjoy the dry, dusty, grey spirit killing normalcy of the daily grind. Schadenfreude!
On the other side of the aisle, CS Lewis comments, “If you are going to see ghosts, you would do well to believe in them.”
Experientially, let me tell you, don't apply that theory to malevolent demons. That lead to my marriage! Not fun.
To paraphrase Vonnegut and misquote RA Wilson at once, “We tend to experience what we expect, so we must be careful what we expect.”
Shakespeare sez: On the bright side, using those methods, I have developed over thirty years of “believing” in it, a quite interesting relationship with a “pookah” I have named “Glory”. To deny some of the things I ascribe to her would imply I am too insane to live in my brain, and perhaps that I am capable of inducing delusions and/or hallucinations in others, so, mostly, I don't talk about her. I do wonder where I would have gotten, by now, if I had initially developed a different theory, like aliens or CIA conspiracy! (Shut-up, Shakespeare)
Very, very interesting account Craig.
Both versions of ghosts can fit with either my soft (morphogenic) or hard (Akashic) versions of my “collective unconscious” theory, but they do seem to pass out of the range of any agreement with Phi..
By the way, Phi, I don't recall seeing any of your posts before. Peace
