Ever passed out due to fear?

I was wondering what people experienced if this ever happened to them. Mostly cause I was in the cardiology theater and the doctor's were stuffing wires up people's arteries and I had to watch and seem interested, (work experience).
 
I felt so close to passing out, felt hot, my vision was blurring and had a shortness of breath that was horrific. After I felt a little better (still watching) I started vibrating a little, which was weird, just tiny vibrations, not anything crazy.

I almost passed out from running for a long time in the heat. That was scary.

Also, cardiology theater...whats that? Are you a student? Because that sounds awesome!

I never passed out due to fear, but I did fall off my chair one time after being tricked by those "What's the difference between these two pictures" flash pictures.  After a minute or so, the picture cuts to a scary ghastly dude screaming at the top of his lungs... after then I was cautious about what flash thingies I look at xD.
 
Oh.. and one time back in high school, one of my friends passed out during a biology video about someone getting a heart operation... his head made a double-thump on the desk =D.

no, but a few people in my labs have passed out during dissections and such. A fear of blood methinks? similar to your expierience

Can't say I have. I believe if I ever see a spider the size of a dog racing towards me I'd probably pass out. Hate spiders!

Nope. I'm a man not a lady. Real men don't feel fear.

@ItBeStefYo: I know that but the term 'cardiology theater' made me think it was a thing you went to like a hospital to view an awesome procedure.

I'm a second year biology major with HUGE interests in human anatomy and cells. I'd love to actually see one in person.

No, I've never passed out period. 

Fear makes me really jumpy, can't say it makes me pass out

Nope. I tend to just squeal rather than pass out when faced with something I fear.

Nope. I'm a man not a lady. Real men don't feel fear.

I've never passed out due to fear.

I dunno man, if bee allergies are common in your family bees get kinda scary.

No, I've never passed out period.

I haven't, but during an anatomy class in highschool, we brought in one of the school councilors in as a guest to tell us about their experience donation bone marrow- it was extremely detailed and super gory, one of the girls sitting behind me passed out and fell out of her desk.

@ItBeStefYo: well school hasn't started yet but when it does, i'm going to be checking that stuff out.

YEAH! FEAR IS FOR PUSSIES! HEAR ME ROAR!

No. 
 
I must not fear. 
 
Fear is the mind-killer. 
 
But in all seriousness, I've never blacked out. I got really close once and collapsed in university - luckily, I stumbled outside the classroom before embarrassing myself and managed to come to a few minutes later. Apparently in-depth discussions on the effects of drugs on the brain are not meant for me to hear.

no, i never did that. 
 
i almost fell asleep at school, history class we were watching some movie. it was a chair that was plastic.

Passed out due to excessive drinking?  Yes.   
Passed out due to fear? No.

No, 
But one time with my friends I watched 7 movies in 24 hours, and during the 6th I got up and sorta jogged towards the stairs to go to the bathroom, and I got super dizzy, fell to my knees, and nearly passed out.  That was fun.

A god doesn't feel fear, so no.

I'm tough

Nope but if I was floating in the ocean and a great white shark came towards me I would shit myself and pass out.

I have. It was some weird thing my friends told me to try where I had to like breathe or something and after all that I had to blow on my thumb (something like that). Passed out for just a few seconds as was the intended result. Other than that though, nope.
