Although I tend to dream a lot, I still remember one from when I was 13. I was going to go to Knott's Berry Farm with a youth group I belonged to and, in my dream, we got there and a girl I'd never seen before was with us. Everyone split up into smaller groups as usual and she was with me and a couple of others as we went into the park. Soon after we got separated and couldn't find her so we searched the park for quite a while before finally locating her in a carnival area near the exits.
So, the day comes for the trip
and there's the girl! Turns out she's a friend of one of the other girls in the group and had come along. We get to the park and, sure enough, she ends up with her friend, another guy and me. Just like in the dream we got separated and I'm having all sorts of déjà vu! Naturally I remember where we ended up finding her so I suggested "Hey, let's check over in the carnival area!" But, when we got there, she was nowhere to be found. I was a bit bummed that my trick didn't work so we ended up doing a long search for her anyway. Finally, we found her, ... in the carnival area. I guess by trying to use the information in my dream I had simply gotten there too soon and she hadn't arrived in that area of the park yet! Still the wildest "future" dream I've ever had.
