Well I know how it is.
The night before some bombings a few years back, I had a dream I was there, dancing with their soldiers, and then there were 3 explosions.
I told my mum when I woke up and she said, "Well, be better keep our eye on the news then!" and she found it funny, until it was on the news later that day.
If someone tells you - trust them. People don't make things like that up.
