Possibly in Michigan

It's a short film, but it weirdly feels like some sort of musical is going on through out, the eery strange music plays, I'm sorry if I'm wrong, I haven't watched it in ages so I don't know the names of the characters, this weird man follows them throughout the mall, their house, everywhere, while I watched it I felt as if I was being watched myself, strange experience but realistic for 1983. Surreal and strange, the quality fine for the times. I feel like I could rewatch it but still feel strange every time. The repetitive music, the eerie atmosphere. Everything about it gave me scary and weird energy.
