I Dreamt Of Flirting Protecting And Time Traveling

I went back in time like the 70s or something but was somebody else. I was a young kid with curly hair. I was at a cafeteria that had outdoor stadium seating. I was befriending some kid for a specific reason but can't remember what. I was flirting with a girl and protected her from a group of guys that were trying to hit on her and be jerks. After I began singing very loud in the cafeteria. When I left the cafeteria I gave that kid I was befriending something like money and he drove off and acted kinda like a dick to me and I was a little flustered since I needed to befriend him for some reason which was why I went back in time. I then went to where my house was as that kid and the person I was trying to befriend was there with my mom. She wasn't my mom but the mom of the person I was acting as. They were chatting and getting along. I then saw the kid that I was portraying there with them. We were in the same room but only he could see amd hear me. I said I was not there or something trying to get him to stop looking and not make a big deal but I just left because he was about to get freaked out. I went outside and watched from the backyard. It was a beautiful fall day and the leaves were falling and was calm. The whole thing felt like I was dropped into a movie halfway through as it was very cohesive and there were goals associated with what I was doing like I was following a plan.
