She was just hit by a car and had a beautiful dream like a romance novel. When she woke up, she actually saw the male protagonist in the dream, and that person was actually the perpetrator!
The things in the dream were so vivid that she couldn't help but become paranoid and fantasize about whether they were from past and present lives. However, when she chased him and asked questions, he just thought she was crazy! She can only think that she is crazy, because his rightful daughter looks exactly like her in the dream, she is not her in the dream!
