Thread: What just happened?

First, I don't know what forum this should go in, but anyways

I was going to get to bed, but I stayed up for an extra hour, just reading and watching stuff. After that I turned off the computer, I began to stand up and then I stretched, It felt very weird, I usually get this feeling when stretching while tired. Suddenly while stretching I could see a lot of things I had seen in my life just roll inside my head, I also tried to do a reality check, that was the first thing I wanted to do when I got that feeling. I could see the memory roll thing for just a second and then I can't remember anything, I woke up lying on the floor a few seconds (I think?) later, and my dad entered the room asking what I was doing, and I was completely lost and felt dizzy.

Tl;dr I sat at my computer longer than usual, when I stood up I stretched then woke up lying on the floor dizzy.

So did i just faint/pass out? Then it was the first time it happened to me.
