One need not be a chamber—to be haunted—
One need not be a House—
The Brain—has Corridors surpassing 
Material Place—

Far safer, of a Midnight—meeting 
External Ghost—
Than an Interior—confronting—
That cooler—Host—

Far safer, through an Abbey—gallop—
The Stones a’chase—
Than moonless—One’s A’self encounter—
In lonesome place—

Ourself—behind Ourself—Concealed—
Should startle—most—
Assassin—hid in Our Apartment—
Be Horror’s least—

The Prudent—carries a Revolver—
He bolts the Door, 
O’erlooking a Superior Spectre
More near—
