One problem. We are dealing with clinically dead people whose hearts and brains have stopped functioning. These people, once resuscitated, report experience which extends into time beyond the point of death.
Possible. I’m quite fucked up. Not as much now as in my early to mid twenties. Imagine having a vice grip headache which is more of a “mind” ache than a real “pain” experienced in the brain. And imagine having that for four years.
Then fast forward to today where I’m regularly in cogent and intentional conversations with a being who, at all stages of judgment on my part, is superior in every imaginable manner to me.
I don’t have the luxury of “owing” a self identity. My self identity, at the best of times, is an allowance on the part of the being. Any “train of thought” I manage to produce is quickly put into perspective by the taunts and menacing torture of the superior being.
Which is probably why I enjoy writing on this forum. It gives me a sense of self where I’m otherwise overwhelmed by the presence of this being.
As far as “I” can tell, my agency in this body extends only to what I absorb through my senses along with volitional control of my appendages (all five of them - and even then I cannot control the fifth with any amount of regularity).
But your report of the “laughing man” should give you pause for thought. Are you able to clearly reason that this being was an extension of your drugged psyche (in spite of how idiosyncratic he may have been in both appearances and mannerism)?
