The boy who dreamed that he had a secret crush had a bad attitude and said that he hated himself.

I think during the day and dream at night. You shouldn't confess. You dreamed that he said he hated you because you were afraid to hear him say so. After all, dreams are not reality. I also had a crush on someone. It feels strange, but I'm happy. I haven't confessed. What a pity. You can test whether he likes you. If the time is right, just confess. I wish you success!
