If you answer "I didn't dream", the other person will think that you are honest and sincere, but you are not very good at coaxing girls; If you answer "I had a dream", the other person will think that you will please girls, but you won't know if you didn't dream, and some will think that you are a little rhetoric.
The above is just my personal opinion, please consider it carefully, and please continue to improve the shortcomings.
