Hello! I'm a seventeen year old female. Over the past year, I have had two separate incidents where I have 'passed out' at two different music concerts. Both occurred while there was blue lighting. I would start to feel a little off, then big black holes would appear in my vision, then I would lose consciousness for a few seconds to a couple of minutes, and be perfectly fine afterwards. This has never happened outside of those two events. My mother has epilepsy and has had two grand mal seizures in her entire life, and I was wondering if what I am describing is simply 'passing out' or if I could have a minor visually triggered seizure disorder. Thanks!
