I hallucinated in a odd place, i was in the school bathroom, sitting on the toilet. I see something move past me like a fly so i look and all of a sudden I’m seeing a whole bunch of stars, like little bright tiny lights just moving in the air. Just bunch of shiny white flys that moved together. I started to freak out and then i look away then look back and its gone.. I'm assuming I hallucinated because nothing was there, and no one was there

1. Is it common for you to hallucinate, and has it happened before?
2. Did you do any drugs the night before maybe you didn't completely sleep off the effects of the drugs.
3. Does schizophrenia run in your family?
If all the answers to the questions listed above are no then are you sure you just didn't get lightheaded while taking a dump and saw spots and mistook them for stars?
