Weird Dream Today

What a weird dream! Today I dreamed that I was on Great Wall Of China and I had never been to Great Wall Of China, and yet I can dream of it... Seems the situation in my dream is peaceful, BUT IT IS NOT!!!! THERE IS NO ONE ON THE GREAT WALL OF CHINA, only me walking alone. My parents is not there. And another weird thing is the way on the Great Wall Of China seems to be endless... I was very panicky and keep on running aimlessly ,and I don't feel tired... Well... All is a dream anyway, at least I have "went" there without all those hassle...
