I like this guy and i think he likes me, but idk. i had a couple dreams about him but theres one that pops...?

we were at an amusement park, having fun with other people, but then we left to go swimming(backround- we go 2 the y and swim and workout together!) we went through a glass door and then were instantly swimming. but after awhile we left the group we were swimming with and we came to an open feild... there was a blanked with a picnic basket, a car, a tree and landscape as far as i could c.(backround- early in the day, we went hiking...so this was the dream that night after hiking with him) we sat down and talked(backround-we have been really open to eachother about alot lately...) but after a while we got up and went behind some rocks and found masks. we put them on and sat back down. we took them off soon after cuz idk y? we sat down again and he walked to the car...well van, and braught chips out??? we enjoyed the rest of the night alone, on the picnic blanket just talking. i was wondering if anyone knew what this could mean or "what it says" about his and i's relationship. (backround- we arent dating, but i hope we could one day...) and should i tell him about the dream????
