Currently, I am reading a well-written book that describes a
woman's experiences at TMI with possible scientific explanations.

Caudill, Maureen. Suddenly Psychic/A Skeptic's Journey.Hampton Roads Publishing Co., Charlottesburg, VA, 2006.

Readers on this site will probably find it interesting.

Read it.  I'll add my recomendations for this one.

The author also had a radio show for a while, though there hasn't been any updates in a while.

Here's the archive of some of her past shows:

Could one of you give a hint about the scientific explanation aspects of the book? I have a long reading list and this one might be one I'd give high priority to.

It's been a little while since I read it, but the author was a computer scientist who worked on AI projects.  She went to TMI foor a last minute getaway not knowing that it would be a 'Gateway' heh heh.  She didn't exactly know what TMI was about.

Her perspective is that of a logical mind looking for imperical evidence, and got it suubjectively through her gateway voyage.

Here's the amazon blurb:

"Suddenly Psychic offers evidence that "paranormal" abilities are a normal part of human consciousness – and what’s more, anyone can learn them! After decades of ultra-rational, "left-brained" existence as a physicist and computer scientist, all of Maureen Caudill’s beliefs about life—and the laws of physics—drastically changed when she began having first-hand experiences of scientifically "impossible" psychic phenomena like spoon-bending, remote viewing, and channeling. This is the memoir of a believer who understands—and speaks to—the skeptics’ perspective. Maureen Caudill has degrees in physics and math from the University of Connecticut and Cornell University and spent more than twenty years as a computer scientist specializing in artificial intelligence and neural networks."
