Recently had a dream where I was some sort of serial killer and was always doing things just right enough to avoid capture – I always picked targets that were alone & whose deaths were unlikely to be investigated (like homeless people), killed them quickly and quietly, did my best to hide and/or destroy evidence, and so on and so forth. Even after law enforcement started catching on, I skillfully evaded them at every turn, managing some very narrow escapes and even sometimes killing a few officers along the way.
One particular moment I remember took place in some sort of empty building (it generally had the vibe of being an unfinished construction, but there were already lights installed that bathed everything in yellow light). I'm standing in the center point of a large room sort of shaped like an U on its side. There's a wooden counter in front of me that blocks off most of the way through, with only a small "gate" serving as a point of entry.
In front of me, there were three police officers, two male and one female, but I knew there were more in the building. They all had pistols, as did I. The first male, who was standing closest to me, had his gun pointed at me and was about ready to make an arrest, but as he was approaching, he happened to briefly glance at something on his side of the counter, and slightly lowered his gun. This was enough time for me to raise my own pistol and quickly shoot him in the head, before doing the same to his two colleagues, who couldn't draw their guns in time.
Then I turn around and move into a crouching position, my pistol aimed at the doorway that was behind and to the left of me all this time. A few more police officers in SWAT gear come running through the doorway one by one, but I'm positioned in such a way that they have to get closer to me before they can have a clear shot. This allows me to shoot into the eyeholes of their SWAT helmets and kill them one by one. There were three more in total.
Afterwards, I woke up.
