I have this crush 😩

Okay, so I have this crush on a guy. So a few nights ago I had this dream about him. I was at the mall with him and a few other people who I didn't recognize except for my dad😶. The rest of the group kept walking while I stopped kinda behind a wall and he was kinda behind us so when he started walking towards me I started walking towards him and I justed KISSED HIM. Out of nowhere. I have only kissed on guy once lol but from what it seemed like the kiss was pretty good and then we almost ended having sex and then I woke up. And all that day I was getting butterflies and before that I just thought that he was really cute and cool right so that kinda confirmed my feelings I guess. Then the next night I had another dream. I can't go into detail it was so weird lol but there were four people, him, another guy, a girl who he tutors with in my drama class and she was trying to help me figure out a way to tell him, ya know? And then that day I started to want to ask him to this dance next month but I still don't really know how😔. Btw he's a senor and I'm a freshman and I know how that looks

Help. Plz.
