Losing shape

Some words loosely fall away into the daylight.
The day soon changes to misshapen evening

Awaiting its night, beyond light, of black sleep.
A night will be round in shape, curtains drawn.

My train will lose its shape in a curve of its line.
The line will lose shape as a train cuts it in two

Turning two lines, two shapes, two phone lines.
The birds on phone lines will run up and down

Losing shapes every now and then triangularly.
The world itself loses its shape,in dark of sleep.
