This is a talk by a neuroanatomist about what she experienced when she had a stroke. There's an 18 minute video (I didn't watch it) and a transcript. Apparently she also wrote a book about it. The transcript is quite fascinating and beautiful. And/or you might look at it as woo-woo, the way some of the commenters do.
