Somnus is not just for napping. It targets the "Void State" between wakefulness and sleep.
Stare at the liquid blobs. Sync your breath to the ring. When the word appears, close your eyes.
Hypnagogia: The "Liquid Light" visuals mimic phosphenes (entoptic phenomena seen behind closed eyelids). By watching them with open eyes, you trick the visual cortex into shutting down pattern recognition, accelerating the onset of Theta waves.
Brown Noise sounds like a deep rumble or heavy rain. It silences thoughts better than white noise.
Delta Entrainment: The 2Hz binaural beat creates a mechanical frequency-following response in the brainstem, forcing a drop from Beta (Active) directly to Delta (Regeneration), skipping the light sleep phase.
A 20-minute session clears "sleep pressure" chemicals as effectively as 3 hours of sleep.
The Washout: During Delta states, the glymphatic system expands, flushing out adenosine (the chemical that makes you feel tired) and metabolic waste products from the neural tissue.
