In a dream, bragging represents a tyrant, an unjust person, or an aggressor.
If the person seen in a dream is already dead, it is a warning for his family.
It also means failure to satisfy one’s religious obligations.
If the person noted in the dream is sick, then it means that he may be nearing his death.
If he is healthy, then bragging while yawning in a dream means affliction with an illness.
