I remember watching this movie when I was really young in the 90s, so I don't remember many details, but it's been bugging me. I think it was about a family on vacation, and it was centered around the teenage son. There was a girl that he knew (from school maybe?) that really liked him and tried to kiss him, but he was extremely not into her, almost repulsed. I think there may have been some weird daydreams of his where everyone turned into zombie-ish things. I know the details are crappy, just thought I'd give it a shot. Thanks!
