Which actress had a coffin in her bedroom and occasionally slept in it?

Sarah Bernhardt (born Henriette-Rosine Bernard; 22 or 23 October 1844 – 26 March 1923) was a French stage actress who starred in some of the most popular French plays of the late 19th and early 20th centuries, including La Dame Aux Camelias by Alexandre Dumas, fils; Ruy Blas by Victor Hugo, Fédora and La Tosca by Victorien Sardou, and L'Aiglon by Edmond Rostand. She also played male roles, including Shakespeare's Hamlet. Rostand called her "the queen of the pose and the princess of the gesture", while Hugo praised her "golden voice". She made several theatrical tours around the world and was one of the first prominent actresses to make sound recordings and to act in motion pictures.

She maintained a highly theatrical lifestyle in her house on the rue de Rome. She kept a satin-lined coffin in her bedroom, and occasionally slept in it or lay in it to study her roles, though, contrary to the popular stories, she never took it with her on her travels. She cared for her younger sister who was ill with tuberculosis and allowed her to sleep in her own bed, while she slept in the coffin. She posed in it for photographs, adding to the legends she created about herself.
