Deep Sleep is a series of point-and-click adventure games created by Polish indie developer Scriptwelder. The series consists of three free browser games in which the player attempts to navigate and eventually escape a dream world inhabited by shadow people. The first game, Deep Sleep, was designed for and won first place in the 2012 Jay Is Games Casual Gameplay Design Competition. Connections between Scriptwelder's Deep Sleep and Don't Escape series were hinted at throughout each, with a much deeper connection being established with the release of Don't Escape 4. Ties between these series and the fictional company Sidereal Plexus have been referred to as the "Scriptwelder Multiverse".
