As the saying goes, "I think about it day and night." Dreaming is just a variation of your usual thoughts or dreams. Don't pursue anything excessively, whether it's a good dream or a nightmare. What you need to do is to relax every day and treat everything and everyone seriously, rigorously, honestly and cautiously. It's true. Bad things are accumulated in our daily life.
