About Sinisomnia
Sinisomnia takes you through surreal, dreamlike environments that you revisit repeatedly. Subtle details shift and layouts change when you are not looking, turning familiar spaces into something alien. Each interaction unsettles the fragile sense of reality as you unravel a fractured consciousness through eerie encounters rather than traditional puzzles. As you explore, the boundary between your mind and the madness blurs, and you begin to question whether you are alone—or the only thing left that is real.
