What does the Sweet safe houses by Emily Dickinson mean?

Sweet - Safe - Houses by Emily Dickinson can be seen as a poem about domestic bliss, like she lives in "stately" homes or, "stately" luxuries.

She loves her home? as the use of repetition of "house" could mean that the house is close to her?

Get the feeling that she doesn't socialise much.

However, the use of sibilance may question her tone, as though she is hissing the Words through her teeth, impression of a bitter tone.

Hope this helps :)
