Deep Sleep

Interested in lucid dreams, a researcher constructs a world in his mind to explore. However, the world in his dream quickly turns nightmarish, and the researcher becomes trapped. He needs to wake up, which is explained when the player finds a telephone saying he "must wake up". Shadowy figures haunt this world and attempt to restrict the player from guiding the researcher to freedom. At the beginning of the game, the player appears to be in a bedroom. To escape, the player must first find a key, then go into the next room and use the key on a locker. A cube with a keyhole in it appears, and the walls of the room melt down. The player will then have to explore the new surroundings and use acquired items to escape. The main obstacle in the game are locked doors, which cannot be opened unless certain items are acquired. After a long period of time, the player finally escapes the building, but still does not wake up. Near the end of the game, shadowy figures start to appear and will advance towards the player. The player will then have to escape the figures, which cannot be killed. Running away, the player reaches a lighthouse with a Shadow Figure inside. The player then turns the light so it directly faces the Shadow Figure, and it vanishes. The game then ends, as the player "wakes up". However, the character is curious about the Shadow Figures and declares that he wants to visit them again.

Following the events of the previous game, the protagonist develops an obsession over the previously-encountered shadow people, and begins to worry that they may be real entities. While seeking information at the library, the world begins to degrade around them, revealing that they are actually still in the dream world. Much of the gameplay is similar to that of the previous game, as the player navigates various rooms and buildings and utilizes various items to advance through the game. Various newspaper clippings give more insight into the nature of the shadow people, which are described as ancient otherworldly entities that exist only in the dream world and desire to escape into the real world by possessing the uninhabited bodies of people in comas or lucid dreams. Towards the end of the game, the player descends down a water well and enters various tunnels, before encountering two eye-like orbs of light in the darkness. The game then ends, and a newspaper article is shown, revealing that a young boy named Cody (whom the player had previously given a tiger plushie) had baffled doctors by awakening from a three-month coma, indicating that the player's action in the dream world can have consequences in the real world.

Picking up at a different point in time from the previous game, the player awakens in their bed, immobile, and sees a shadowy figure in their room, which briefly attacks before vanishing. The player then fully "awakens" and exits their room, only to discover that they are still in the dream world and resume their attempts at escaping. After finding various items and proceeding through various rooms, the player enters a series of underground sewers and tunnels, inhabited by massive dreamworld predators known as "bottomfeeders" that the player must evade. Upon escaping the sewer system, the player enters a room explored in a previous game, where they discover that their uninhabited body had already been possessed, and they are now a shadow person themselves. Upon facing this realization, the player encounters another human traveling through the dream realm, who begins to flee. The player is then given the option to either let the human escape unharmed and remain trapped in the dream realm, or possess the human's body and leave them doomed as a shadow being.

In January 2021, Scriptwelder announced Don't Escape 4 (using simply Deep Sleep as a working title).[3] The official website provides the synopsis, "You embark into the depths of the eerie realm of dreams. You will have to face the horrors of the worst nightmares to find what you seek."[4]. The genre of game is described as a unexpected combination of the point and click and roguelike genres, with horror themes. A release date is currently not set.
