Ghosts
chamber/house distinction
Dickinson rejects the gothic setup. A chamber is a single room, a house is a building—but she's saying the real haunted space is neither.
whiter host
White in Dickinson often means blank, emptied out. These internal ghosts are more terrifying because they're versions of yourself drained of identity.
Abbey gallop
Classic gothic imagery—ruined monastery, pursuing stones. She's listing this as the *safer* option compared to meeting yourself.
moonless
No light means no witness, no external reference point. You can't verify what you're seeing is real.
superior spectre
The final twist: all your physical precautions miss the actual threat. The ghost you can't lock out is already inside.
