Sounds very Afraid of Monsters-esque. Occasionally, the game (which is a first-person-shooter with Silent Hill-ish city environments) will dip into nightmare sections where you have to parkour your way through sketchy mazes, which are induced through drug overdoses as your character is an addict. You should check it out, unforgetable Half-Life mod.
