Cyberpunk style: A sleeping figure viewed from above on a futuristic bed, their head wrapped in a sleek black headband emitting soft neon blue pulses. Translucent holographic brain wave patterns float and ripple above them like digital aurora borealis, showing distinct layers of deep purple, electric blue, and soft cyan representing different sleep phases. The bedroom has a dark, moody atmosphere with subtle tech elements—ambient LED strips along the walls, a glowing charging dock on the nightstand casting cyan reflections. The waves visualize the transition between REM and deep sleep as flowing data streams. Rain streaks down a large window in the background, city lights blurred beyond. The overall mood is intimate yet technological, capturing the intersection of human biology and personal analytics. No screens showing text, no visible devices with interfaces—just pure atmospheric visualization of measured sleep.
