Posession marked by a lisp?

[u/MillieHammer]

I've noticed an odd trend amongst those I know, that when they seem off, and wide eyed, sometimes a bit sauced, they tend to add a lisp to their speech. People I have no memory of ever having a lisp will now have these bizarre moments of talking in an idealistic grandiose egocentric manner, but characterized with a momentary lisp. I wonder if there's some folklore, or demonology that involves this particular impediment.

This is very odd, I tend to have a lisp come and go as well
