Why do i keep having constant dreams of the same person?

Infatuation comes to mind.
I have the same thing with Walter Brimley - that man haunts my dreams.

You may be thinking about that person for all the time or you may think when you go to bed.

Jarsha's right! Or it could mean the person thought of you before they went to bed. That's usually how it works.

You may having good respect on him
