Yeah I never really thought it was real either. I didn't share everything, but the info he told my mom was way too specific.
I really am a skeptic when it comes to psychics and stuff like that.
I just find that they say reeeeally general things and the people who want to believe will find a way to apply it to their lives.
For example, There used to be a show called 'crossing over with john edwards'...and a lot of people think since he's on TV he MUST be a real psychic, but when I watched it, all he would do would be go over to a section of the audience and say some SO general, like "I'm sensing someone over here had a grandmother whose name started with M"...then someone would raise there hand and say "My grandmother was named Margret" and he'd say something like else really general and do a 'reading' and everything just wound up being like "your (loved one) wants you to know that they're O.K/are sorry/forgive you" etc.
I read a book once about how psychics con people, they just take cues from their speech (like if they talk about a person in the past tense they can safely assume they've died and can 'contact' them). Body language, speech etc, they just take cues from that to do their readings.
Anyways, I'm obviously not trying to put you down, but as I said, I'm really skeptical of those things, but it sounds like you had an interesting experience. Maybe someday something like that will happen to me and make me believe.
Dude, you know what there are always going to be doubters about this sort of stuff, but what I feel is more important in this encounter is that is affected both your Mom and You not in a negative way but a positive way and there is absolutely nothing wrong with that at all.
