This actually reflects a kind of pressure. You say you like her, but I'm afraid she's not close to you. There are others around her. So you hope that no one wants her and no one competes with you, so in the dream, she is terminally ill and ugly, and no one plays with her. At this time, you will repent and become a great being like a savior. Say something so heroic. All these reflect that you are weak in reality, so you long for strength in your dreams. Sometimes the less people get, the deeper their obsession will come true in their dreams. This is daydreaming.
Teenagers, chasing girls still have to work harder to improve themselves!
