For much of the past three years, Vashti DuBois, 56, has been dealing with chronic insomnia—ever since her husband was killed in a car accident, reports Newsworks.

It’s all part of “A Good Night’s Sleep,” the latest exhibition at The Colored Girls Museum, which DuBois runs out of her charmingly well-worn Victorian home in northwest Philadelphia.

Almost every room of her house doubles as an exhibition space for the show, which DuBois describes this way: “A discovery by the colored girl of what’s keeping her awake at night, and what might we prescribe to help her get sleep.”
