Nightmare by Megademo

In the quiet suburban town of Crestwood Falls, the boundary between dreams and reality shatters when an experimental sleep therapy program goes horribly wrong. A malevolent entity known only as The Shade escapes the subconscious mind of a comatose patient, manifesting in the real world under the cover of night. With glowing eyes and a form that dissolves into mist, it hunts those who dare to fall asleep.

"Kopfkino" - German for vividly imagining a scenario or playing out events in your head, almost like watching a movie in your mind.
