QUOTE(Isaiah @ Dec 3 2006, 12:32 AM)
As a general rule, spirits speak to when spoken to, or when something reminds them of their fondest memories. Essentially, they react to stimulus akin to that they experienced during their first existence. So, in an area like mine, where I live across the street from a graveyard, sometimes I'll say something or make a noise that sets them off and I'll hear them talking amongst themselves, or to me. Most of the time it's a minor inconvenience, but it is possible.
If you're completely silent, I kind of doubt they're spirits unless they desperately want to get their message heard.
Infact I have raised my connection with many dark spirits and speak to them via telepathy, clairsentient feelings, and with my actual voice, esp. during meditation. At the time where I was hearing these voices, I was speaking to these spirits by means of telepathy and thoughtforms, though I didi not concentrate long enough to understnad what they were saying. I did first think that it was only my mind, but I realised that it was too real (almost exactly if someone was whispering into my actual ears physical, except for the vibrations).
