That does sound a bit off maybe she was trying to put in your mind how much worse things can be. I dont know though it sounds (no offense) a bit batty. Maybe she just liked thinking about torture and was possible a sadist or something. I couldnt imagine what that was like. My first gruesome thing I saw has stuck in my head and created nightmares for ages so I couldnt imagine what your imagination must be like because of that. Its a good question as to why she did that I agree with manic she may have mental health issues of her own with no idea of how to handle them.
