Psychosomatic

"How body from spirit slowly does unwind
Until we are pure spirit at the end."

Spirit bodyish I am.
I just don't know what that means.
If being spirit were good,
You'd think more folks would try it.
And why the prefix "psycho,"
Meaning crazy dangerous
Or possibly wholly faked?

But it fits my frame of mind.
My body suffers for it,
House that cannot shake the ghost
That was never really there.
Seat of emotions and soul,
Puff of invisible air.
Nothing can do such damage.
