This has only started to happen recently, and sometimes it just gets so annoying and distracting.
Near the end of my Freshman year at school (I'm going into my Sophomore year now), in every classroom I was in, the light above me would always flicker. There'd be no pattern to it either, at least from what I could tell, because it flickered randomly.
It would be in every single classroom I was in. It didn't matter where I sat, if there was a light above me it would flicker.
I would ask friends who had the same classroom for a different period if any of the lights would flicker, and they would say no.
I recall it flickering the most during Algebra class, and that was the class I zoned out most. At home, whenever I had a headache or zoned out, the light next to me would flicker like crazy.
One day during finals, I was in the cafeteria listening to my ipod (I was sitting alone at a table). A janitor came by and told me to move and he pointed above me and said something about the light. I looked up, and the huge light above me was seconds away from burning out. T was flickering in this maddened way that freaked me out.
After lights have burned out in my room I'd change the bulb and they would still flicker. Sometimes it just gets so annoying because all I can see in my room is the flickering of the light at this random pattern.
I've tried controlling it before, but I don't know how and focusing on it makes it stop.
It's only started happening recently too.
