If a story were set a house, which image would best symolize secrets?

Answers:

One possible answer for this question would be: a secret room.

Explanation:

It the setting of the story is a house, the image that would be best to symbolize the theme of secrets would be a secret room.

This room can be unkown for all of the memebers of the house or can be kept by one of them.

The secrecy of the room would be surrounded by hidden keys and mysterious hallways.

as for symbolic actions, the narrator's tearing down the wallpaper in an attempt to find the "woman" in the wallpaper represents her struggle to retain or regain her sanity.   the wallpaper has been part of her confinement and by her tearing it down, she is freeing herself from that confinement.
