In an unknown way for me

Imagine a person who first, at his own free will climbs into a chest and closes the lid. And then he begins to suffocate in this chest. And when the attack of claustrophobia brings him to complete exhaustion, he suddenly opens his eyes and understands: there is no chest! He disappeared, and the person just lies on the floor. All the stories in the book are about this. Well, or for this. So that all these chests are disappearing, one by one. The story "Forty -thirds" was published in the collection "Nada", the story "Head and Lira sailed according to Goebra" - in the collection "cards on the table", it was completely impossible to do without them, the chests are scattered very well from these stories.
The remaining texts are published for the first time
