What does it mean if you keep dreaming about this person you used to like many years ago and keep seeing your self getting back together with him?

he probable still loves u, but it might just be nothing

A different response:

Dreams reflect the dreamer's own thoughts, feelings and fears. They do not provide any information about anyone else's thoughts or intentions. This dream could suggest that the dreamer still holds feelings for that "someone," but it could just as easily have been triggered by something that reminded the dreamer of that person.
