I have a very vague memory of a movie I saw as a kid. I must have watched it in the ’90s but it could have been a movie from the ’70s to ’90s. I don’t remember which part happened when but I’ll try my best. I didn’t watch the whole movie either, just a few scenes. It was about this woman and her son in a winter setting and it was like no matter where they went, something totally bizarre and scary was happening. They went to a middle school or high school and all the kids looked either possessed or demonic or like ghosts. They wanted to hurt the woman and her son but they ran. Then she is driving and to her right she sees a guy standing in the snow and he suddenly falls through. I think she investigates this and finds a facility underground and there are a bunch of people fighting this machine/alien; not really sure what. Like I said, very bizarre but I would love to find out what it is called and watch it as an adult.
