Analysis of They say that shadows of deceased ghosts

They say that shadows of deceased ghosts
Do haunt the houses and the graves about,
Of such whose life's lamp went untimely out,
Delighting still in their forsaken hosts:
So, in the place where cruel Love doth shoot
The fatal shaft that slew my love's delight,
I stalk, and walk, and wander day and night,
Even like a ghost with unperceived foot.
But those light ghosts are happier far than I,
For, at their pleasure, they can come and go
Unto the place that hides their treasure so,
And see the name with their fantastic eye:
Where I, alas, dare not approach the cruel
Proud moment that doth enclose my jewel.
