@voidhz4: Headphones on. Watch the light travel — forehead, crown, temples, back of the head, base of the skull — and feel the sound move with it. 174Hz with a 6Hz theta binaural beat (171Hz left ear / 177Hz right ear). The tingling follows the glow. 🎧 Headphones required — the beat only exists between your left and right ear. Full 2-hour version on the channel 🧠 Comment where you felt it first 👇 Not medical advice.
