i have a weird one, but apparently im not alone with this:
I kept having REALLY realistic dreams when i was younger. Like, reeeeally realistic. They always had strange situations though, which i couldnt imagine ever happening with people i didnt know etc.
I also used to have really strong deja vu often. So, well, you know where this is going. I started writing down my dreams and low and behold. Those realistic ones really often actually happened. For example one time i dreamt about talking to people i didn't know yet while eating fries in the cafeteria of a swimming bath, when a small kid approached us, asked something before getting sent away to play with the others by the person on the opposite end of the table from me.
About 3 months after this dream I became a part time overseer for this summercamp thing. another 2 months after that we went on a trip to a swimming bath, where the situation from the dream unfolded exactly like in my journal.
freaky stuff. didn't happen again for a long time until just recently
