Well, I always told my kids in lieu of pulling the plug on the cable that watching all the paranormal shows on tv was a form of studying demon activity. By demon activity I mean those Atlantian creatures who were advanced enough to avoid the preAdamic chaotic earth scene, much like the rich and famous could do so now with their prebooked flights to the outer limits. Anyway, said child now has encounters that I think stem from that, but she doesn't realize that she gave an opening. Anymore than she was almost 'naturally' gay after a traumatic event that if it had not been for a "malebonding" experience where she was beatup when being mistaken for a boy sent her back to a more feminine perspective, would have not realized it as anything but a natural occurance.
Not to say that you were seeking the experience but I think that things we may not realize (oiji board as extreme example) do bring on events.
