Folks, everything that I’ve been reading about memory palace construction and Sherlock’s Method of loci is telling me that this padded psych ward cell isn’t a mind-fabrication; it’s an actual place he’s been, somewhere in his past.
“First, mind palaces do exist. People have them. I can’t because I’m not clever enough, but clever people can have them.
You construct it out of spaces you’ve actually been in. You start in a house you live in and you put things in it and then you maybe join it to a theater you know well or something.
So you’ve got a map in your head of places with which you’re familiar. The look of his mind palace would be conditioned by where Sherlock had been.”
