That has happened to me only in real life. I checked for a number of dream signs of course but it was real, either that or I've yet to wake up from it. You see, sometimes I recognise something all of a sudden. The place I'm standing n gives me a view of something that triggers it, or a certain number of things in succession leads to it, but it's like a deja vu, only I can sit there when it begins, knowswhat is going to happen next for a few seconds, maybe even a minute, and then it dissapates, but it NVER feels like deja vu, where you feel it's happened before, and then realise you're mistaken. In fact, sometimes, the things I experience are dreams I'm remembering and everything that I remember that happens next does. It's kinda freaky actually,but intrigueing as well.
