I haven't had ECT, but I have had the same experiences with books and even movies or streaming shows on TV. We are financially strained but ended up paying for Amazon Prime for a year, so certain shows and movies have free streaming. I start one series, and I didn't remember most of it and still don't even though I have apparently already watched it. I don't even remember the big reveal of the murderer at the end of Season 1. Now, I have not watched past Season 1, but I want to watch the other seasons, and I've had to go back and re-watch all of season 1 (I'm finally nearly done with that as I do remember parts of the plot as I see them happen again on TV.) I ended up doing the same with a book I read maybe early March, and I had first read it maybe a year ago because according to the copyright, it was not out before then. I even checked online in case I had a paperback or later release, an I didn't.

It is a very disconcerting feeling.
