How can you describe a room in an insane asylum which Blanche is living in I am writing an epilogue for the play A Streetcar Named Desire?

The room in the asylum is stark and sterile, with pale, peeling walls that echo the sadness of its occupants. A single barred window lets in slivers of muted light, casting shadows that dance ominously across the cold, tiled floor. The furnishings are sparse—a narrow bed with thin sheets, a small table, and a solitary chair—reflecting the desolation of Blanche's mind. The air is heavy with a sense of confinement, both physical and emotional, as she grApples with her shattered past in this bleak sanctuary.
