Analysis of Haunted

Gulp down your wine, old friends of mine,
Roar through the darkness, stamp and sing
And lay ghost hands on everything,
But leave the noonday's warm sunshine
To living lads for mirth and wine.

I met you suddenly down the street,
Strangers assume your phantom faces,
You grin at me from daylight places,
Dead, long dead, I'm ashamed to greet
Dead men down the morning street.
