I blacked out for the first time earlier

[snoorkel]

I was sitting at my desk and suddenly felt really weak and hazy and like I might vomit, so I got up to go to the bathroom, about 5 steps away I felt something like a massive blood rush and lost my balance and blacked out before I hit the ground. I came to a second later with my head sideways on the floor trying to figure out what happened, it took me a second to realize where I was.

I then realized I hadn't had any water for many hours (probably the whole day), and had been the beers earlier so was probably dehydrated

it was kind of scary, has this happened to anyone else?

not quite. last night, at the end of my long shift in the end stages of my long piss i was staring at the racks of the wall in the kitchen bathroom, when i experienced a swift and acute physiological effect. my vision seemed to swell with lucidity and this abject vividness, like polish lacquer mixed with absurdity had been pumped to the nerves while my frame swayed imperceptibly and form weakened. there was an odd incipient feeling to it, like that of yellow delirium churned with mild confusion and shock, and a sickening fear. as soon as i could sense what the fuck was happening it was no more, and i stared around for a moment as if born into another world, then proceeded to serve tea and cappuccino. the nagging thing is i was completely sober all day with rest and nourishment. i thought, 'damn, those rotting holes must have eaten through something'.

A few weeks ago, I was having a pretty intense workout at the gym. 30 minutes into it, I began feeling unusually tired, so I walked back to the locker room to get my stuff. As I was walking back from the locker room, my vision began to fade and I became very dizzy. I walked up to one of the personal trainers and asked him if it was possible to overtrain yourself. He asked me to repeat myself. He couldn't understand what I was saying. I then propped myself over the front desk, and began to explain myself. That's when I almost completely lost my vision and my hearing began to go. Everything seemed very distant. He brought over a chair and a bottle of gatorade.

As soon as I sat down and sipped that gatorade, I began to recover. Apparently I had extremely low blood sugar, likely since I hadn't eaten in six hours (very stupid of me). I drank the bottle of gatorade and completely recovered. I was able to safely drive home after that.

Pretty scary stuff.

[don't let's]

I've gotten close a few times. The last time it happened I Had just stood up on my bed, got all lightheaded, couldn't stand and fell down and started having spasms for a couple seconds. So I got really, really close that time.

i already know why it happened. i just didnt eat enough that day. i shouldve eaten something an hour or so before working out

This is me. I would just throw up and get migraines though.

I passed out during church once. We were kneeling and it was too warm and all of a sudden I was looking at the details on the ceiling and was confused as to when all the detail work was done on my bedroom ceiling.  My friend thought it was some kind of god experience, but I was just dehydrated.
