Does it matter which 7 hours I sleep?

I've noticed that when I sleep from, say, 11-6 as opposed to 12-7, I feel very different upon waking up. Even just shifting everything one hour late, when I get up at 7 my mornings are pleasant and alert. If I wake up at 6, even if I had gone to bed and fell asleep at 11, I had to take a nap somewhere in there. Are there studies that shows which hours you sleep actually matter? Or are all of this in my head?
