ok, this might be a hard one cus i don't remember much.
1. The ending went like this: a man stood in the room with a half-melted recorder. His wife was nearby. Before he turned on the recorder, his wife had told him that it was actually a nightmare or a vision or something. But then he turns the recorder on and hears his dead daughter. Both were shocked.
2. It might have something to do with furnace. In any case, there was an episode with a burning room.
3. Among other episodes there were such that when the man looked into window on the opposite building, his reflection didn't move whereas he did.
1. is seemingly nonlinear (several levels of action)
2. ends with a couple threatening a group of persons with guns
3. among other episodes, a man uses a rather unconventional weapon.
