Deep Sleep

Deep Sleep is the first of three games in the Deep Sleep trilogy, which includes Deeper Sleep and The Deepest Sleep.

Plot
The game is played in the first-person, and begins with what seems to be the player character having woken up from sleep. However, after making a certain interaction with objects in the game, the walls fall away revealing dark mountains in the distance. After exiting the starter room, a phone will be heard ringing in the distance, and when answered a message stuck on loop plays; "Wake up. You have to wake up. You have to wake up. You have to escape. Or I won't. (after this is an indiscernible mumbling, which seems to end with "beware of the Night Folk"). Following the call, the player is expected to collect items essential to escaping the nightmare, and in doing so explores a setting that appears to be hotel of sorts, featuring a bell and numerous key-slots. The character will encounter one of the "shadow people" after retrieving a pickax. As the game progresses, the large stone wall in upstairs hallway is broken, and reveals a dark beach with a lighthouse beyond. From this point, if the blue crystal has been taken from the box, the player character will be increasingly surrounded by Shadow People, forcing them to the top of the lighthouse. The game ends after a short fight at the top of the lighthouse in which the player character "vaporizes" one of the creatures using the crystal which ends the nightmare however the player character wishes to once again go back to the deep sleep.
