Dream About Helping Girl With Multiple Personalities

In my dream many people were dying and I was helping a girl who was being hunted. She had been kind to me and felt like a sister. Towards the end of the dream, I sought help in a house, and the girl I was helping began exhibiting signs of having multiple personalities. This caused the person I sought help from to become scared. When I inquired about what was happening, she told me that the girl's other personality was coming to get us. I was confused until the girl started exhibiting erratic behavior. The person I asked for help began to pray and call for assistance, causing me to run and lock myself in a room. That's when I woke up.
