Writhing sheets

A ghost amongst others,
Rattlin chains,
I wouldn't bother,
Knowing it's floats,
And won't discover,
Where it comes
Or goes,
it knows,
it has no author,

just another white sheet waving
Paying respects,
To the life It's framing,
Never regrets,
What it's taking,
And so
The ghost remains till
You figure out it's faking.
