Yup, I've heard the same many times over the years. It hasn't really gone away, it just died down. This is just a resurgence of the same kind of moral panic. Hysteria fueled by social instability.
There's a book similar to "Michelle Remembers" called "He Came to Set the Captives Free.". It's very similar. It's the harrowing tale of a woman who escaped satanism and lived to tell her story, confiding in the author. Her story was entirely discredited and the author lost her medical license for administrating demerol (a powerful sedative) to all her patients, whom she believed were demonically possessed.
She's still actively speaking about the horrors of satanic ritual abuse, although her audience is mostly very crazed Christians. I've met a lot of people who bought her story and even though it's wild, with stories of meeting the Pope (who is part of the worldwide satanic cabal) and journeying to Mecca (because Muslims worship satan) and fabrications.
I think in a way, this is all a part of Evangelical's desperate attempt to justify their Trump support - he HAS to be chosen by God for SOMETHING, even though he's accomplished virtually nothing for the Kingdom of God, so this fairy tale MUST be believed in.

I still can't really believe it...
