Why am I having Dreams about the guy I like?

I’ve had a crush, an on and off crush (right now it doesnt seem like alot but i guess it could be), and ive had 5 or 6 dreams about him in the past one or two weeks and dont worry, thier all good. Except for one that I dont understand. I was sitting on a chair in the corner of a room and the guy I like is standing in the corner. He was angry at something, not me and then I closed my eyes and he started throwing bouncy balls at me, with my eyes still closed I caught them. And the weirdest part is there were dozens of opened boxes, all evenly spaced, inbetween us. I want to know why he keeps showing up in my dreams, and what that dream means.
