You find yourself trapped in a dream. Capture anomalies, meaning locations or phenomena that deviate from reality, with a camera. By doing so, you might be able to return to reality. There are two modes: Normal Mode and Nightmare Mode. In Normal Mode, an anomaly will always occur at each time. However, in Nightmare Mode, there are instances where no anomaly occurs. You will find themselves wondering whether there are no anomalies present or if they simply haven't been discovered yet. I recommend playing in Normal mode for the first game.
