Disturbing Dream is bothering me!! Help!?

So I had this disturbing dream and it made me cry. I had dream I was in line like a prisoner, and a group like ISIS or similar to them forced a bunch of us in line to drink poison, I think it was cyanide causing us to die. This dream will forever stick with me. I remember my thoughts, I was fearful and so sad knowing these were my last moments. I thought about the universe and how I never made a good impression. I could actually feel the poison in my throat. It was the most disturbing dream ever, the group was also cutting are hair and making mean comments. Some people in the line like me were scared and fearful, but others were joyful and happy.

This dream has been disturbing me for days. It makes me have so much sadness when I hear of innocent people being executed in the middle east. I don't know if my dream was a cry for help or just something random. But I feel like it has some meaning. Please serious answers, I can't stop thinking about it, it was so lifelike. What do you all think?
