Jeepers Creepers where did you get those PEEPERS!

Well, although I haven't had a doctor appointment yet, I have had something strange happen to me. I woke up a few days ago with my left eye slightly lower then my right. Well... I shouldn't say eye, I really mean eye lid. Brian was concerned and ran me through a battery of tests and neurological exams, and there was something a bit strange. My eye that was slightly closed was the only one reacting to some of the tests while my other eye just gazed forward. I didn't have any problems seeing, just my eye isn't reacting. So, what could this mean? I have no idea! Brian is thinking on it and had some ideas, but I personally think it is just scary. If anyone out there has some ideas please let me know your insights!!
