Oh and on the first question.

I am not familiar with the 'subliminal dynamics course', however as one who possesses a very large and old metaphysics library personally collected over decades I can assure you that near nothing published last 50 years is new except in some terminology use and of course some emphasis for application.

There is simply not that much new in ideas regarding mind, thought, human psychology, metaphysics and even most physics modern or otherwise that I could not comfortably find tucked away in some old book written 100 years ago.

Easily, the vast proliferation of information on the worldwide net not withstanding.
