A - I think L and your mom and your brother are right, you should stop obsessing about the light. You have enough going on in your life right now, you don't need to be worried about a possible intruder or a ghost (I vote ghost). L and your brother may be right, you might have just imagined/dreamed the whole thing. I know that there have been times when I was deeply stressed that I would have very vivid realistic dreams that left me wondering if things really did happen. Take a deep breath, have some herbal tea, think of something nice and wonderful, close your eyes and relax for a few minutes. Call me if you need to.
