Why do i feel better the next day when i sleep on the floor rather than my bed lol?

ever since i can remember ive always preferred sleeping on hard surfaces rather than a bed, i slept on the floor last night and i slept better and feel better today.. maybe im an alien? when i was young i asked my mom if i could sleep in the kitchen Lol i still remember cause i really wanted to sleep on the table or the linoleum floor
