Another world

In 2019, you lived in a small town on the outskirts, in an old apartment that resembled a senior citizen's home. Unfortunately, you had to rent just such a place because you were a poor student. Strange things were constantly happening in the apartment, no matter the time of day: a glass would appear in an unexpected place, or a door would slam. You tried to find the source of these sounds, but couldn't, and it was very strange. One night, at around 12:15 AM, you heard a door slam, probably in the kitchen. You decided to check it out. At the end of the hallway, you spotted a black figure with sharp claws. Because of the darkness, you couldn't make out its face, but the faint outlines of horns were discernible. And this figure began slowly approaching you... And then the apartment seemed abandoned: the windows were broken, the doors were missing in some places, the kitchen was completely destroyed, and your bedroom? There was blood and almost everything was broken. If you look out the window, the world has changed too: the trees are all leafless, the sky is red, the ground is almost bare of vegetation, and it seems like there is no one on the street?
