This is tinfoil hat stuff.
You mentioned "reformed" several times. Reformed folk tend to be very theologically discerning (Eph. 4:14) and they would not touch it with a ten foot pole. BTW, that’s also why most reformed folks stay away from speculative futurist dispensationalism. It's just plain bad theology.
I can understand why some pentecostals might get caught up in it since they have already opened themselves to spiritual oddities. But I would not think it is normative even among pentecostals.
Parading ignorance is sooooo informative.
