OP: 'Demons pose as anything that is attractive to humans: sexy girls, and the promise of wealth, gold, and power, riches, etc.'

It sounds as if you are confusing the experiences you have been having with religious doctrine to which you have been exposed. The products of the unconscious of which you speak are not capable of 'good' or 'evil' the way you describe them as demons.

The word 'occult' itself means dark, so the use of the word 'dark' in the title of the OP to describe the word occult is superfluous.
