I have a few times
Once when I was a kid I was singing in a church choir and I fainted. I had no idea what had happened until I woke up surrounded by worried old people lol. They gave me biscuits and a kwenchy cup and I felt better.
When I was a teen I kinda went through a phase where I wouldn't eat much or I would just live on small bits of junk food so it happened a few times then. Teens, don't do this because it will happen to you.
It only happened once when I was an adult and I'd donated blood for the first time. I was in a store, shortly after my donation, and I felt all the signs (hot, lightheaded, unsteady/shakey etc) so I walked to go outside so I could sit. Instead, I fainted then and woke up with a security guard kneeling down beside me and another standing in front of me, stopping people from staring. They asked me a few questions, then took me to the café and got me a free cup of tea and a piece of cake.
