My two cents...
First of all, good thread! Interesting, reasonable posts, and with an ex-jw link in most posts. With all the flaming going on, it's nice to see a thread doing things right. Also, it makes me wonder if leaving JWs has a statistically significant link to interest in paganism.
Second, I've had a few interesting experiences: precognitive dreams, visualization that produced exactly the desired result, some accurate premonitions, and some highly useful/accurate tarot card readings (read the cards for myself). Nothing earthshaking, otoh I haven't put that much energy into it, what with being a JW.
Third, and last for now, I find the problem is not with the event, that is, not with what happens, but with the interpretation of the event. For example, people feel a presence, and decide it is a demon, or a ghost, or an alien, or Xenu... Why not just work with what happened? A presence was felt. Great. Was it useful? Scary? Can it be felt again? You get the idea - don't use the phenomena as proof of whatever you started out believing. In most cases, there is no way to prove anything.
Fourthly, and really last for now: all non-normal phenomena seems to hover on the edge of proof. There always seems to be just enough evidence to convince those with direct experience, but never enough to convince others. It's weird. Michael Crichton, in his book Travels suggested that such phenomena may be state-dependent, that is, dependent on the state of the experiencers, in much the same way that your experience of food depends on the state of your hunger. Made sense to me, and worth thinking about.
