Down from my ceiling
Drips great noise
It drips on my head through a hole in the roofBehind these two hills here
There’s a poolAnd when I’m swimming in
Through a tunnel
I shut my eyesInside the cabin I make sounds
In through the tubes I send this noiseBehind these two hills here
Fall asleep
And when I float in green grass of tunnel
It flows backDown from my ceiling
Drips great noiseIt drips on my head through a hole in the roof
Behind these two hills here
There’s a pool
And when I’m swimming in
Through a tunnel….
I shut my eyes.I shut my eyes
