So about 2 months ago I was in the line at macdonalds, getting a meal then all of a sudden I felt very sick and felt like I needed to sit down, my vision went black like how it does when I get up too fast but when I kept blinking like I usually do to make it go away it didn't, and then I fainted and fell to the ground.
Before this I had never fainted. I hadn't drank or eated anything that day before hand but this is not uncommon as it is actually rare for me to eat breakfast so I do not believe this was the reason. Anways, 3 weeks later I was lying down in bed and it was like confetti was falling from the sky but it was like bright lights and it was slowly taking over my vision, I however did not faint.
Then yesterday I was at a wedding standing then I felt like I was going to faint again so I sat down and instead of my vision going black it was getting taken over by a bright light.
Why was it a bright light and not my vision going black this time?

This actually happened to me once before. It was REALLY frightening. I got up from the loving room sofa to go and make food (As I hadn't eaten that day!) and everything went black. I was still moving, it was like I'd just gone blind. Blinking didn't help. After passing out for a while I woke up and everything was okay again.

I'm not sure how much the light was relevant, but not eating will definitely contribute.
