More Use For Haybales

My friend and I were doing a hardcore world where we had no ability to find sheep unless we travelled thousands of blocks. We did have the ability to farm though. I think that if we had the ability to sleep on haybales, with possible effects like bad sleep that temporarily decrease efficiencies for a short period of time after waking up, or even sleeping for only half the night on one, would be a cool addition to Minecraft, as it adds a new ways to play the game, but still adds a bit of challenge and strategy.
