If you are interested, you can analyze the ideas in the book. Of course, the information I have communicated with you here is limited, which may be inaccurate, and some of it needs to be analyzed in combination with your specific environment.
First, you say two dreams. The first dream is that a male classmate confessed to you, and then you woke up feeling flustered. If you have felt that there is a certain gap between you and your boyfriend before, we can assume that this dream is your psychological self-suggestion: I may lose my current boyfriend, but I don't have to worry, because there are still people who like me. And your confusion shows that you don't want to lose this relationship, and you are still serious about your boyfriend. Of course, these are all your subconscious, and you can't obviously realize them. Of course, there are other triggers, such as what you suddenly remembered before. This should be combined with your own experience.
The other dream is what you emphasized. A week after you broke up with your boyfriend, you met the boy in your previous dream again. In your dream, you had some relationships. Then I heard the news that this classmate committed suicide. Then you were sad and forced to jump off the building.
After breaking up with your boyfriend, you may feel very frustrated and feel that you have no company, which is not what you want in your heart. At this time, your subconscious may realize itself in other ways. Of course, these implementations are sometimes indirect. You don't have to think about how to treat others. . . Then you heard the news of your lover's suicide, and it was heard here. You didn't directly intervene, which means that your lover died suddenly. "Suicide" has nothing to do with you. In that case, no one will know your story. The reason for this idea is simple, nothing more than a cover-up.
Then you are sad. I guess here that the sadness in your dream is not because your lover committed suicide, but because of your separation from your boyfriend. Being forced to jump off a building by others means that the reason why you separated from your boyfriend is you.
I want to sum up, your second dream is to say: I was sad after my boyfriend and I separated, but I hope I don't care. The main reason for breaking up is me, or maybe the person in my dream ruined our relationship. I will never let that man go.
Just combine the information you gave. Many of them are guesses, and the details are up to you.
