Is it normal that some faces appear on my dreams and i dont know them?

I dreamed about those people i don't even know. I don't see their faces either on real life. What does it mean? The boy on my dreams keeps on appearing on another scene. I don't know. He's my boyfriend on my dreams then i pushed him away but after he leaves i realized something. I asked my auntie on my dreams. This auntie is like that boy on my dreams too because i don't know her face either but she's close with this boy in my dreams and i told her if can i see that boy again so that boy appeared again in my dreams :/ i dunno why im dreaming about those people i don't know :/ Is it normal?
