Dreaming of my crush again?

Date: 6/21/2016

I had a dream that my crush lived right near me like next door and he went into my back yard idk why and I got a Coca Cola bottle and then he threw it near our neighbors house across from his and we quickly ran to the back of my backyard and hid there and he was like "It's gonna explode" 2 seconds later it explodes and we hid there for like 20 minutes and kept laughing.... Why do I keep having dreams of my crush?
