I put a pot on the stove, turned it on, and never turned it off.
The rest was told to me by my mother-in-law (may she rest in peace).
I think the implication is that your mother-in-law may not have accurately recalled the sequence of events that led her to drop by. For example, if she'd dropped in and nothing was amiss, would she have come to believe she was taking orders from a Saint? The overarching narrative was
probably created after the fact, if your mom-in-law's mind worked anything like the rest of ours.
IMO, the faulty memory explanation is not particularly satisfying (it doesn't account for the aspects of my experiences that involved other people, major alterations in my routine or direction that I believed to be the result of an irresistable impulse, and facts I could not have known) but I certainly can't rule it out.
I've often thought of trying to keep a journal of every such impulse and dream and the following events, but since I haven't done it, I've got nothing to produce against the faulty memory argument, or even to demonstrate convincingly that these events actually occurred. So I normally keep them to myself except in the company of other people with similar experiences.
