The first kind is familiar people, because familiar people have names. The name is the meaning of dream interpretation. Name is a person's motivation. If you often do this person, it means that you have problems in love and work. Because only these two things are repeated every day.
The second is a stranger whose name is unknown. Express your destiny
If he treats you well in his dream and you are attached to him, this person is the only thrill, who can treat you well all his life and has a deep eternal fate with you.
Fate can be met but not sought, so cherish it. That person can give you happiness. With him, you will never feel lonely, not lonely in dreams, nor lonely in reality.
Don't take it seriously!
