This probably sounds utterly weird, but I don't remember any occasion that was freaky in any way. Then again, I've been communicating with them since I can remember, probably before I was able to talk humanese, lol.

What does get a bit weird at times is when I'm having a conversation with friends/family/acquaintances, and suddenly some spirit pops in, wanting me to convey something to them. Of course, if I don't know them well, I'm extremely reluctant. ;-)
