Spravato (esketamine) creates a dissociative state that temporarily loosens the brain's default mode network — the system responsible for rumination, self-referential thought, and entrenched emotional patterns. During this window, the brain is unusually receptive to new input. Music doesn't just accompany the experience; it actively shapes it.
Research on ketamine-assisted therapy consistently shows that music influences the emotional valence, depth, and integration of the experience. Patients who use intentionally selected music report more coherent, processable sessions than those who use random playlists or silence.
The wrong music — too familiar, too lyric-heavy, too rhythmically aggressive — can anchor the mind in ordinary consciousness and blunt the therapeutic effect. The right music creates a container: a sonic environment that supports surrender, emotional processing, and the kind of non-ordinary awareness that makes Spravato work.
