Deep Sleep

Deep Sleep is a nightmare-themed classic Flash horror that made Newgrounds' front page, now revived in the browser through Ruffle: you are stuck inside a nightmare dream, something lurks in the darkness, and something in the depths of your own mind wants to pull you even deeper. Someone will escape this dream for sure — the question is, who is that going to be? It is free, needs no download, and sinks you into the deep sleep straight in your browser.
