I dreamed of my sister more than once recently, and I have been looking for her whereabouts in my dreams. She and I separated after the college entrance examination. It hasn't stopped recently.

You didn't even leave your phone number? At least you have WeChat. It means that you often have such dreams when you have her in your heart, thinking about it day and night! Don't worry, you are friends and you will meet one day. If she knew where you were, she would come to you. Don't think too much, she will appear naturally.
