My Dream last night

Snapback to September 21, 2017, the first day of autumn. I'm just an American here in Michigan. My last dream was about a man with a snapback that kept coming after me, looking for me, with a knife in his hand. Before the dream ended though, he pointed a machine gun at me. I found it pretty much impossible to wake up from this dream! I found people running around, not knowing if they were running from or towards the guy. The male cops showed up at the man's apartment but backed down when they found a guy tied to a chair. I was hoping the cops would take him into custody but didn't because he had two female officers forced to sympathize with him. I felt like I was going to vomit. Please help me. May the higher power that rules over us please help me, for I have bad things happening to me, even in my sleep!
