Have you ever had epilepsy? (not sure how to translate. Epileptic crisis?)

I've had seizures or whatever it's called twice in my life. Once when I was 10 or 11, and one last year.
They were not light-induced, so I can play video games

1st time : I was in some inflatable thing where you jump around. This one was like an obstacle course with a slide at the end.

I then thought : "Hey, it would be fun to slide on my knees!" And I did.

I bounced from the top of the slide, and crashed on my nose.
Even if the slide wasn't in metal, I got hit pretty hard. I felt very dizzy and eventually fell down,
having seizures, being semi-conscious (I could hear people talking).

2nd time : It was at school. We were playing badminton.

At one time, I stretched my arm a lot to try hitting the ... pigeon?
I felt something in my neck (a nerve probably got stuck or something like that).
A few seconds later I was having seizures for 20-30 seconds.

Fun Fact : This is the only school day I missed that year (not even a single snowstorm)

Not So Fun Facts : - Rarely being sick = Rarely missing school
- That year sucked
