Have you ever had a dream where you were in a place you always wanted to go, and you felt like you were there, only to wake up and realize it was a dream

I had that happen to me once. I dreamed I was in (Believe it or not) Japan (Or, at least, what I pictured Japan looked like) I always seemed to be fascinated with that place. It felt so real, because there was actual people I interacted with, places that looked so real, and I even brought my laptop, because I worried I would miss out on things here on Fanpop (I may be addicted to Fanpop :P) But, I was REAL pissed when I woke up. Why can't I just go to Japan
