Thread: What's this called and what does it mean?

The most logical explanation is that you are experiencing DejaVu on a rather large scale. Yes, it is quite common to dream that you have experienced something before, or you have seen something before, or been somewhere before.

However, you must realise that while you are dreaming you are in a altered state of consciousness thus you are not fully able to think clearly. So in thinking that you have experienced an event before you may auto suggest that you have been there before without fully thinking it through.

Hope that answers your question.

I often think I've had a dream more than once, but I've just decided to ignore those thoughts, because I know I haven't. Also, you do lose pretty much all reasoning in dreams. I had a dream that I was nomiated VP for the presidental election (lol) even though I knew in the dream that it was already over.
