I remember seeing a horror movie on television (not sure if it was a made for TV movie or not) when I was a little kid (probably around 1982 or 1983). People kept going into a house & up the stairs into a bedroom on their right. As soon as they entered the bedroom someone would kill them. It was not lit inside the house, and overall very dark. I have researched several movies that could be related, such as Friday the 13th part 2, and parts of the original Black Christmas. However, I still do not believe it was either of these. Let me know if you have any suggestions. This has bugged me for years.
