I don't sleep well at night

I had a nightmare last night. Me and all of my closest and not so close friends were all dressed in black and had bandanas tied around our noses and mouths. We were formulating a plan. I don't remember any of the details of our plan but I do remember being with my friend Elliot and going through peoples yards and garages and underground tunnels to get to a certain spot in downtown to meet our friends and go through with our plan(clearly, this is about the RNC). There, we were greeted with Riot Police on horses. At first awaiting nervously to see what we would do. We all just started marching towards them and chanting things in unison. Immediately the police started to come at us. They got off of their horses and were slamming kids to the ground and spraying mace in their faces. They were just aimlessly spraying mace everywhere, all around. Like, as soon as they started to feel slightly threatened, the answer was to just aimlessly spray and swing until they hit as many as possible no matter who it was. I had started running down a side street by this point. The whole dream was sepia toned and set in the night time in downtown St. Paul. I looked around the streets and I could hear the screams of agony in the distance but I was alone. I was running as fast as I could to get away from all of this and I remember realizing that even being at least 2 blocks from the chaos by now I could slightly smell the mace and taste it in the back of my throat and as soon as I realized this, I woke up.

I woke up terrified and wanting to hug every single one of my friends that were involved with the protests and further, arrested and charged with ridiculous charges.
