After having an awkward college roommate for a year in a single room-dorm, I obtained a sleeping mask and some earplugs. Now that I'm in an apartment with 3 other people, I still find occasion to use them. Perhaps you may find value in such occult devices? Mind you, this is a side-stepping of the issue. If your sister behaves in such a way in response to your request for a sleep environment on a regular basis, then perhaps it's not in your best interest to maintain a familial relationship. I don't know what your financial situation is, but moving out may be in your best interest. Find a roommate who's easy to negotiate with.
