Who has seen European and American horror movies, midnight movies?

What I saw a long time ago should be that the killer in the old horror movie suddenly came to the unlucky cinema in the middle of the night, and then there was a mixture of movie plot and real life. I think the horror is that the killer has appeared, but the audience is still watching the movie leisurely. Even watching the people around you appear on the screen is not alert, and there is a feeling that the killer is in control ... of course, the final "ending" is still quite good. After a ridiculous and horrible movie experience, my sister gave full play to her imagination, saved her brother and left the only survivor. I wonder if she will be regarded as a deranged patient by ZF in the follow-up investigation. ...

We should be talking about a movie, right? I really forgot that the movie I saw was called midnight movie. ...
