Ending
Spoilers:
A will leave their room and will walk out of it. Once outside, A will be in a place known as Snowfield, with various objects representing items that A found during their journey in the Dream World. Walking north from the entrance will lead to A's Living Room (Which A calls My Living Room). As soon as A enters the Living Room, their Mother is seen in the kitchen sleeping on the table, with a knife beside her. The Living Room consists of a kitchen, the actual living room with a TV and a couch, and A's Other Room (which is called My Room by A), the which could've been A's Room when they were little and still lived with their mother. Once entering A's Other Room various toys and objects are seen (A half-solved puzzle, a xylophone, 2 stuffed animals, a picture/drawing of some red flowers, a notebook with 2 markers beside it, a desk, and what looks like a crib). After interacting with the drawing/image of the flower, and the xylophone, A will be able to start coloring/drawing on their notebook. The screen will then fade to black and we are now controlling A's Mother. The room changes to vibrant colors, with blood in various places and worms moving all over the Living Room, now called Somewhere. Mother has a knife in her hand, and will have to go to A's Room (now called Something). Once in, we see A as a monster, and when interacting with them, Mother kills A. The screen then fades to black, before displaying an end title screen.
