When I was 20, I went on a date with a very beautiful girl with long dark black hair. I was driving my car and we had gone out to eat and a movie. When we drove back to her apartment, we sat out talking in the car for hours. About two hours into our conversation, the hair on the back of my neck stood up and I got goosebumps. When I looked over at her, she suddenly looked very old with grey hair and a wrinkled face. I freaked out and jumped out of the car when she asked me what the matter was. The only thing I could think of to answer was that she suddenly looked old. She began laughing and she gradually transformed back into her youthful appearance.
She then told me that what I saw was her grandmother checking up on her to make sure she was safe.
