Rapper
To dream of a rapper or rap musician represents an aspect of yourself that likes to feel good arrogantly showing off. You or someone else that likes to brag or show off to others about what you have or how much more important you are. It may also reflect a person in your life that scares you that all their priorities are based on showing off.
Dreaming about rappers may also reflect competitive conflict that involved threats or arrogant displays of grandeur to embarrass opponents. An arrogant cold attitude that belittles competition every chance it gets. Feeling good bragging in public about being better than other people.
Example: A man dreamed of seeing a rap star that loaned him money. In waking life he felt that a friend who had done him a favor only did it because he was looking forward to using him later on to show off to other people.
Example 2: A man dreamed of seeing angry rap stars yelling at him. In waking life he was running a very competitive business that required showing off and bragging in public to embarrass the competition that he was superior than they were.
