The exact origin of this darkness clip is unclear, which is common for files passed around 4chan's /v/ board and TF2 community soundboards, where users tagged it alongside party and shitpost audio. It spread as a reusable sting for fake-serious edits: a dramatic blackout cue in the same family as the Fears to Fathom notification and the Inception button. Because it is short, dark and instantly readable, editors kept reusing it for ironic horror moments, and that loop of reuse is what turned a throwaway board sound into a small lasting meme.
