The Siberia hell sounds come from the Well to Hell urban legend, a story that spread in the late 1980s and 1990s claiming Soviet scientists drilling in Siberia recorded screams from underground. The tale was later shared widely online with low quality audio presented as that recording. In recent years the clip was reused in the Mr Incredible becoming uncanny meme, assigned to Phase 7 as the stages grow more distorted, and it still circulates in horror edits and creepypasta posts.

Creepy screams and rumbling said to be the Siberia hell sounds from the Well to Hell legend, used as Phase 7 in Mr Incredible becoming uncanny edits.
This is a short, distorted burst of wailing voices, deep rumbling and chaotic screaming linked to the Siberian hell sounds legend. The audio feels crowded and panicked, as if many people are crying out at once under heavy echo and static. In the Mr Incredible becoming uncanny format it marks Phase 7, where the smiling character has turned deeply unsettling and the joke shifts into horror. The sudden wall of noise makes a normal image feel cursed, which is why editors pair it with the darkest, most corrupted phase of the meme.
