TIFU I reported a teacher talking alone cus I was creeped out

This happened when I was in 8th grade (years ago). Also, English is not my first language so pls excuse any grammatical errors and whatnot.

I was an altar server at a church with a school which I also attend. The church held an evening mass and dinner for a celebration. So after the mass, everyone went to the hall to have dinner. Since I was an altar server, I had to stay behind to fix the things used for the mass. While I was there, I realized there’s a person left at the church. Mind you, this was during the night. I immediately got scared cus all of the horror stories about the church. I went closer to have a clearer view and it was one of the teachers seated at the pew at the middle of the church. She was having a full conversation with someone but she was alone- like full on loud voice with hand gestures. Ofc my immature brain immediately thought she was talking to a ghost or smth creepy, so I left and called the other youth to witness what was happening. We all got scared and just left her there. The next day I was so bothered with what happened because she was also my Science teacher. I reported her to my Language teacher. So, she too, at her adult age, panicked, cus she thought it was a possession happening ( a lot of possession events happens at my school) and decided to report what happened to the priest. So, the priest called my Language teacher and Science teacher for a meeting.

Turned out, that night she was having a breakdown cus her brother just died and was talking to God.

Oops. My bad.

TL;DR: I reported my Science teacher cus I thought she was possessed, turned out she was just having a mental breakdown cus her brother died.
