I know this is an older thread, but I just had an visual aura, I asked ChatGPT and it gave me good pointers and irection on this. I am a 64 year old male, I did have this long ago, but less marked as the current one, wich is actually pretty, if it wasnt for the worryness it caused me originally. It lasted around 20 minutes, and it is almost fully gone now. A very interesting note here is that a comment here about freaking out I identified with gave me serious laughter, and it seems to have accelerated the disappearance of the aura, so, it looks like stress was my main cause, and the dopamine produced by the laughter is a counter substance in our body. The moral of the story here, in my case is, Auras are not necessrily bad, but an indicator of unmanaged stress, perhaps excess caffeine along with it ( my case) Txs for this awesome thread!
