One need not be a house;
The brain has corridors surpassing
Far safer, of a midnight meeting
Than an interior confronting
That whiter host.
Far safer through an Abbey gallop,
The stones achase,
Than, moonless, one’s own self encounter
In lonesome place.

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

last stanza: you can't keep out the major intruder which is part of yourself.

Fourth stanza- The herself behind her exterior mask may even startle the assassin hid in her apartment and he will the horror's least.
Fifth stanza- The prudent carries a revolver and gaurds the house, overlooking the greater phantom (poet) is...
