Dream of

I saw i'm talking with a pretty whome i don't know.she and i were sitting on juniour class chairs and there is two red colour juniour class tables infront of us.one is for the girl and other one is for me.we are talking to each other.we are sitting in the middle of a strange collage ground.When the collage bell ranged we stand up to go home.I walk behind her.the collage ground is like abondoned.while i'm walking after her i saw the national flag was laying down on the ground.But i walked without piking it up.After few steps,i turn back to pick it up.Then i saw a black dog tearing the national flag with its teeth.
