Don't think so -- at least not reliably. Nobody predicted the 9/11 attacks. No psychic has predicted where bin Ladin is. I don't see any psychics finding missing children or preventing crimes or accidents. Every single one of the many doomsday prophets through history were wrong.
idk. i've had short timing future readings where i'm thinking about something and someone else outside my mind says it. i also get deja vu alot. i've also gotten further readings but they were pretty vague and unimportant. i had this one vision when i took my friends hand and concentrated i was in a club and about to have lesbian sex. so far i'm straight. idk
No more than *you* can "predict" the future and wind up with a lucky guess. Most "professional psychics" and mediums also practice the art of cold reading.
