Somnium

Somnium is a first-person horror game about spotting differences in a salaried worker’s apartment room. You play as a worker burdened by debt and stress, whose sleeping problems lead to a repeating dream. Memorize what the room normally looks like, notice any changes when you wake, and follow the correct steps to advance time until dawn and escape the loop.

Observe the room

The first time you wake, it is before midnight; remember the state of the room. After going back to bed, you wake again in the middle of the night and must check whether anything has changed or disappeared. If the room is unchanged, go to the toilet and then return to sleep. If it has changed, go back to bed without visiting the toilet. Choosing the wrong action sends you back to the beginning at midnight.

If you wake somewhere other than your bed, you need to get back to it as soon as possible. The game automatically saves each time you sleep, but making a mistake restarts play from midnight. A playthrough takes 10–60 minutes.
