C Gm F C  (C Gm F Fm)
Go back to sleep and dream
Tip down your blue sombrero
The van was a time machine
that's broken down in tomorrow
and I know (and I know)
by the sound (by the sound)
of the rain (of the rain)
as it falls on the ground
that this love
is a shelter with holes
if you stay here too long
you'll be drenched to the bone

Go back to sleep and dream
Cling to the ones that you love
hide em in your memories
so you'll remember exactly what was
when you wake (when you wake)
to the sound (to the sound)
of the rain (of the rain)
as it falls on the ground
in this life
is a shelter with holes
if you stay here too long
you'll be drenched to the bone
