" I feigned sleep until my mother left for school, but even my eyelids didn't shut out the light. They hung the raw, red screen of their tiny vessels in front of me like a wound. I crawled between the mattress and the padded bedstead and let the mattress fall across me like a tombstone. It felt dark and safe under there, but the mattress was not heavy enough.
It needed about a ton more weight to make me sleep. "
― Sylvia Plath , The Bell Jar
