Dreamcore

It's located at the end of a huge wheat field where your home used to be. Beyond it is a random Dreamcore-style dimension: any random space with small changes or unstable objects.

It appeared in your house three days ago, on the wall on the left in the living room, but you didn't notice how slowly it grew. Something told you that you shouldn't touch it.
NEVER.
(it grows from your doubts)

An ordinary house in Dreamcore. A small living room, an old sofa, windows, and a door to the street. On the nightstand is an old square TV that shows either static, weird commercials for various things, or Angel TV. Opposite the front door, at the opposite end of the living room, are three doors: the left one leads to a small kitchen with everything you need, except the microwave often falls through the countertop, and there are plants growing on the wall by the window. A second microwave (not working) is on the ceiling. A different to-do list appears on the refrigerator every day. The right door leads to the bathroom. The mirror reflects nothing, and sometimes the water doesn't flow, or only flows cold (the water is a bit unstable). Strange sounds are sometimes heard in the bathroom.
central: an empty room with windows and a door in the center that does not open.
On the left in the living room there is a door to the second floor with two bedrooms, one closed, the other user-owned, and a bathroom, the same as on the first floor.
