WEIRD DREAM I HAD!!!!

a couple of weeks (perhaps days) ago, I had a dream where i was on a school trip to perform at a theatre. we had gotten there by train. on the train, everyone was so kind and polite. i thought i could trust them. the next thing that happened once we FINALLY arrived at the theatre to perform, i remember myself getting tortured until there was nothing left of me. 

does anybody know the meaning behind this?
