Dreaming has a lot to do with poor sleep, but thinking about things during the day has a lot to do with improving sleep.
Everyone says that dreaming means thinking during the day and dreaming at night. Personally, I think it is still subconscious, because dreaming is in sleep, and things in the subconscious will come out. You can also say that you dream during the day and dream at night. If I can help you, I hope I can adopt. Thank you.
