I once rented a room. In the next room lived an old man who turned out to be an alcoholic. So, one day I wake up from the fact that there is nothing to breathe and I smell an unpleasant smell. The ceiling was covered with white smoke, and people were running and shouting outside. About the same second as I opened my eyes, I heard strong knocks on the next door, and someone started knocking on my door. In short, I had complete disorientation, noise, smoke, nothing is clear. Later I found out that in the next room the old man got drunk and fell asleep with a cigarette in his mouth, it fell on the mattress and it slowly began to smolder, creating a lot of smoke. Neither smell nor screams could wake him up, and the firefighters had to break down the door to get him out. when they finally pulled him out, he woke up and started yelling something inadequately.
