Space Dementia is a track by English rock band Muse from their 2001 album Origin of Symmetry, written around heavy piano passages inspired by classical music. The title refers to a term for the psychological effects imagined for astronauts on long missions. This short excerpt focuses on the H8 lyric, a section fans quote and clip for edits online. Shared as a brief soundboard cut, it survives less as a full song moment and more as a compact cue for dramatic obsession and spiralling thoughts in memes and fan videos.
