I can remember listening to a radio program with my mother about strange luminous balls of fire coming out of kitchen appliances called ball lightening
I've actually seen this stuff... a once in a lifetime event, but it was from an airplane, not in my kitchen. Cool beyond explaining...
Pretty much anything that was a no-no was classified as demonized. Music, tv, movies, games etc etc etc.
The concept that yoga was demonized scared me as a kid. The thought that stilling your mind would allow demons in was pretty disconcerting. I can remember thinking about it in reciting scriptures over and over in my head so that it wouldn't be still and allow demons to come in. Does that make any sense?
I can remember certain Disney movies were big no-no's. Aladdin, Sleeping Beauty etc... anything with witches or magic.
