I have deja vu & amnesia - I think I've forgotten this before...
I've had it happen (reasonably) regularly for years & in my case I am pretty sure what causes the feeling.
At a young age (about 15) I had an incredibly vivid, but mostly meaningless dream. Briefly it was me driving up a highway with a friend beside me, through high bamboo on either side. There was a crossroads up ahead & my mate told me we had to go straight ahead but when we got to the intersection we had to turn left. The sign said Mackay.
Couple of years later, I left on a road trip with a school mate - he'd turned 18 & got his license & it was holidays. Although I didn't have a license I did some of the driving. Up in Queensland, over a thousand miles from home & where I'd never been, we entered sugar cane country. We were driving along with cane fields on either side - 8 foot tall cane - & he said (from the map) we had to go straight at the next intersection & I told him we had to go left. We were both right. The map said straight but the sign said left.
Ever since then I've kept note when I have those 'specially vivid' dreams & they always come to pass. Never been anything significant that I know of - just random everyday events that I somehow have seen in a dream a couple of years earlier.
