Friends taken away

Date: 7/11/2016

So I was on like a train type transportation and I was sitting next to my friend Dani, and there were two people across from us but I can't remember who but we knew them. Then I saw one of my friends (Alex) upside down being carried by someone who may of been a police officer and he was knocked out. I started freaking out and I couldn't get up or move to help him. Then I see another one of my friends (Joseph) and he is also being carried upside down and he is more beat up then Alex was. Then I just start crying really hard and go to hug my friend Dani but she wouldn't comfort me and she was like "You are fine". and then I woke up in the middle of the night.
