Brown noise paired with a cave texture instead of wind, with a longer reverb tail than the rest of Sleep. Despite the name it reads less like open wind and more like an enclosed space, the occasional low resonance filling in behind the drone.
If Night Wind's actual wind-based version of this idea feels too open some nights, this is the more contained alternative, same brown-noise foundation, different texture layered on top.
The cave texture is generated on your device rather than played back from a file, so the pattern never lines up the same way twice across a whole night.
