The one I like was where an OCD patient went flatline on the hospital bed, went above her body and memorized a 12 digit number way up on the top of the breathing machine.
She later told the nurse about it. The nurse checked on the top of the machine and sure enough, the lady had the 12 digits exactly correct.
I recall a story like that where the person who died “saw” a single tennis shoe lying on an outside ledge of a building that she couldn’t have possible known was there. Later someone checked, and there was the odd tennis shoe that for some reason had been tossed up there.
I have a lot of tentative beliefs about all of this; but one is that when we are near death, senses that we possess but that are not often apparent are magnified. I had extremely odd experiences with my grandmother when she was dying and I was caring for her, that made me believe this.
