Oneirostasis

Oneirostasis is a first-person psychological horror and anomaly-spotting game you can play solo or online with one friend. Each night, decide whether there are any anomalies in the house. If everything is normal, go back to bed. If you spot an anomaly, escape through the front door.

You are trapped in a dream

Each night, you "wake up" in the same house, where anomalies may be lurking. Your goal is to return to the real world. Go back to sleep on safe nights, or escape through the front door on nights with anomalies, to gradually strengthen your connection to reality. Choose wrong, and you will become lost in the dream.

Play online with a friend

Too scared to play alone? Invite a friend to brave the unknown with you! Two-player co-op includes additional anomalies designed specifically for playing as a pair.

More challenges

If you're brave enough, don't miss these challenging ways to play:

• Dark Mode: Play with all the main lights switched off.

• Evidence Mode: There are anomalies every night, and you must photograph them. The anomalies also become more challenging.

Some of the screenshots above hide anomalies. Have you spotted them?
