Don't pulsed magnets create eddy currents (electricity) in the body? So the end result would be the same as a contact device / zapper. Electrical current running at 15 Hz.
Those Orgone zappers all have Neodymium magnets in them.
I have a Silverado, another orgone zapper, and it's definitely affected my dream state.
I used to leave a magnet next to my pillow, connected to a zapper. I remember it affecting my dreams even when running at 2500 Hz and 30000 Hz.
