Grey-equalized brown noise at 3.9 with a barely-there twenty-second swell

Night Cocoon is like lying in a tent while a slow wind pushes against the canvas: a deep, soft roar that leans in and eases off so gradually that you only notice the change if you listen for it. The grey equalization gives it a rounder, more even feel than the raw brown presets.
Its color value is 3.9, and grey EQ is enabled so the bass does not dominate at volume. A triangle-shaped pulse at 0.05 Hz makes one linear ramp up and down every 20 seconds, which reads as a slow tide rather than a beat. The fade-in is a full 30 seconds.
This is a favourite for people who like a hint of motion but found Deep Sleep too obviously rhythmic. Midnight Hum is a close cousin at 3.85 with a slightly faster sixteen-second cycle, while Slow Descent stretches the cycle out further to 25 seconds. Try all three at the same volume to hear how much the cycle length changes the feel.
