Even as JW, I was inexorably fascinated with the occult. I had my share of psychic experiences early on as a child but those were quickly extinguished (or buried in dreamwork) by my mother's insistence that what I was experiencing was undoubtedly related to some recenlty purchased garage sale item. There would be burnings, incantations (er, I mean supplications) to Jehovah to expunge.
Now, I do work with alternate "realities". I would encourage anyone interested in the occult to study it (you know when you're being called). If it scares you, then you probably are not being called or not ready to engage. It also, imo, requires a more mature (not to be insulting) relationship with the Universe/god/gods. "They" do not require or respect groveling or fear of any sort. You will attract darker spiritual energies if you approach the veil with a fearful, grovelly energy. It is just like meeting other beings on this plane. You will attract what you put out. Sometimes that's good and sometimes that is bad.
Love and Light,

p.s. I have yet to encounter the "shadow". Has anyone here had that experience who would care to share?
