I remember a few years ago I turned the TV on part way through a movie and I think there was a teacher or something and a few teenagers were vampires of some sort because they didn’t show up in the bathroom mirrors but they took a kid on a car ride then they’re heads became a skeletons face and the screamed at him and I think the guy died.
Also at the end of the movie the teenagers died because of a train I think? I just remember it was a bright white light and there was a good teenager who killed them with the train or something.
“Sometimes They Come Back”(1991 TV movie)?
Here is the full movie from youtube.
