This story reminds me of my one, real near-death experience.
When I was in my mid 20s I was having some sleep issues, with incidents of (I now realize) the not so uncommon phenomenon of waking sleep paralysis. Several doctor visits led to an MRI at the local hospital. The day of the procedure, I was prepping through the paperwork and questions and had put on the gown and was about to be lead into the MRI room.
One of the questions I was asked concerned whether or not there was any metal in my body -- a plate in my skull, a replaced knee, or some such. Dental fillings were safe. I answered to the negative, but just before walking into the MRI room, I recalled that in the prior year I had a root canal done, during which the tip of the a aaaa a dentist's tool snapped off in my tooth. The dentist opted to sanitize the site and backfill, leaving the piece in place (after consulting a dental reference book on the matter...). Alarmed recalling this, I was advised by the concerned MRI tech to call my dentist's office from the hospital and asked if the dental tools were made with a ferrous metal. After a bit of telephone shuffling, I was assured that they were not. So, I headed to the restroom one more time before reporting that I was ready to go for the MRI procedure.
Then, all of a sudden someone started banging on the window from the MRI control room. It turns out my dentist had called back to the the MRI department and reported that, upon contemplation, he took one of his dental tools and touched it to a refrigerator magnet... and found that there was attraction. The piece of metal broken off in the root of my tooth would, in fact, be attracted by the machine's incredibly powerful electromagnets.
The procedure was, of course, cancelled for that day and I was told by the MRI operator that if the dentist hadn't called back to the MRI center in the hospital with this news, the result would've been catastrophic. He explained that a tiny pinhead embedded in the center of a bowling ball would've been torn through the ball and shot into the MRI machine. It would've been a similar scenario with my skull and brain as the bowling ball.
I ended up delaying the procedure, having an endodontist surgically remove the piece of metal in a lengthy procedure. I finally went through with the MRI, which went smoothly; nothing troubling was found during the test and no large chunk of brain and skull departed my body. That's my near death experience.
