I had a strange semi-nightmare dream last night. It felt like I was watching a movie or a TV show, and I was one of the characters.
The dream took place in a high-rise condo, apartment, or hotel room. The occupants of a room were being killed by a group of criminals who occupied the upper floor of the unit. What happened was the guy who lived below the criminals' unit was "locked in" by the bad guys upstairs, who secretly surveilled and had remote access to the occupant's unit. He couldn't get out of his unit. The bad guys would then release poison gas within the unit below, or set off a small explosive to kill the guys living below them. Why or how the villains did this, it wasn't totally clear. At some point, one of the guys (from my point of view) managed to get out into the patio or balcony area and hide behind a secluded area. One of the bad guys found out and shot the guy (or me).
Since I was still alive to witness what transpired next, I assume I was watching a movie or a TV show. The bad guys were also kidnapping young boys to work for them. One of the kids put up a "Help Me" arrow sign by the window that pointed to the bad guys' unit, and the authorities were notified, although the sign soon disappeared.
While on patrol, the authorities were looking for the bad guys in the streets, and they spotted a group of shady-looking men who started firing at the police. My perspective changed, and I became one of the authorities who shot all the bad guys in the street. I don't remember what happened next, but that ended the criminal operations. Everything looked realistic in my dream.
