Another possibility is that you are still thinking about her. Even after two months, many things have happened around you, which may gradually cover up your love for her, but it is only to cover up, not to erase. When you sleep at night, this love crawls out and comes to your heart. You can also say that you miss her in another way. I think you can recall whether what happened during the day touched you, so you want to see her in your dream.
In fact, many people's dreams at night are related to what happened during the day. A casual little thing may happen during the day, and you will forget it as soon as you turn around, but at night you will have dreams related to this day.
