I got told that it could be indeed the case that my brain continuously has small seizures but only from time to time they break trough and cause the pain and auras which I would then experience. They wanted to measure the brainwaves to figure out if that was the case. That would also somehow fit what OP said, so I guess this is known in the medical world already. Or at least something in that direction.

Only that's not how auras seem to work. The current understanding is that they are caused by cortical spreading depression - a slow travelling wave which depolarizes the brain cells it passes through. These don't just happen randomly in healthy controls.
