it’s not quite deja vu [two words ;)], although i get that too. it’s a sensation (some might call it an aura i think) that something specific will happen and then it does.
simple example: i was in camp and we went to the laundromat to do our laundry. as i was coming down from the bus, i had this ‘vision’ that the place is going to flood – and about halfway thru our trip, one of the machines started to back up, sending water all over the floor of the laudromat, pretty deep water!! it was sorta creepy.
it sounds unreal, like i’m making it up. i think that’s because of the wording, but i honestly have no idea how to describe it accurately.
