Newbie here, found this site since I make creepy threads in fb. I decided to share my story as well.
When I was a grade 7 student, our school decided that recollections will be overnight. So we were all happy about it because we can sleep with our friends. It was 5:30 pm when our advisers told us to line up in the open court because we are about to enter the auditorium (it was where we will have our recollection). So it took a lot of time, while we were observing our surroundings, one of my friends told me that a silhouette of a tall man was standing in the covered court (I can't clearly see him, but pretty sure there was). So the time comes that brothers started lecturing then suddenly, the lights turned off. But after some minutes, the lights were back.
After the lecturing of our brothers, our chaperones told us to sleep. I easily fell asleep cause I'm a sleepy person (they also turned off the lights). Then suddenly the lights were on again, I was annoyed because I was already having a good sleep. I didn't really care what was going on so but one adviser was talking to my batch mate so I slept again.
Then it was morning, so we prepared until the brothers come and start their lecture, until the recollection was over.
It was Monday (recollection started Sat or Fri), so this is when we were already talking about our experiences and shiats. I asked my friend what happened when the lights turned on, it was like 12 am. She said that one of our batchmate almost met an accident. An electric fan almost hit her head while she's asleep. Those who were still awake that time says that the electric fan screws were slowly removing until it almost fell into her. It was like someone was screw driving them. The electric fan on her side (batchmate who almost got into an accident) was not that even broken. Also, my best friend said that a shadow of a man was standing outside on the window (that window was on our side, so basically it was front of us, we were also facing that window). Some of our classmates and batch mates who were still awake until 3 am saw it too. It was 3 am because my best friend checked the time on her phone when she saw the shadow of a man.
The staffs who checked why the lights suddenly turned off in the middle of our brothers lecture said that the lever for the lights was switched off. It was also impossible that the lever fell and so it was switched off since the it was kind of stiff. It was also impossible if us students since we were all in the auditorium. Not even our chaperones since they were with us. And especially, staffs will not even make a prank.
I would agree with Alina regarding the wall fans. It is possible for the screws to be loosed by just the mere force or pressure of the motor and blades. It actually happens in construction sites where I was the Project Engineer. And another cause is faulty installation because as what you had said, the fan was hanging from the wall.
And about the lights turning on and off, I would say it's a normal thing to have brown outs in the Philippines specially in the province.
Base from what you had submitted, you were not scared or anything, I would recommend not thinking much about it and just cherish your recollection memories. Recollection are supposed to be happy moments based from my own recollection back in highschool 😁
