The 'Dead God at the Bottom of the Mariana Trench' meme emerged from the intersection of cosmic horror and internet 'void' culture, often featuring haunting imagery of massive skeletons or eldritch entities submerged in the deep ocean. It taps into thalassophobia—the fear of deep water—and the existential dread of discovering something ancient and powerful that has long been forgotten. Primarily popularized on platforms like TikTok and Reddit, the meme often pairs eerie visuals with unsettling audio to highlight the insignificance of humanity compared to the mysteries of the deep. It serves as a visual metaphor for repressed memories, forgotten history, or the terrifying scale of the unknown.
