for the volunteers who come and stay overnight, i've tacked up slumber song, by sassoon:

Sleep; and my song shall build about your bed
A paradise of dimness. You shall feel
The folding of tired wings; and peace will dwell
Throned in your silence: and one hour shall hold
Summer, and midnight, and immensity
Lulled to forgetfulness. For, where you dream,
The stately gloom of foliage shall embower
Your slumbering thought with tapestries of blue.
And there shall be no memory of the sky,
Nor sunlight with its cruelty of swords.
But, to your soul that sinks from deep to deep
Through drowned and glimmering colour, Time shall be
Only slow rhythmic swaying; and your breath;
And roses in the darkness; and my love.
