Getting my wisdom teeth removed
It's worse than it sounds.

I was born three months premature, and that's a fascinating story in and of itself, but I'm only mentioning it because I think it's somehow related to why all this happened.
See, I was about 17 when that fateful visit to the dentist told me that my wisdom teeth looked like they were impacting. I shrugged and said I'd wait and see what happens, thinking nothing of it.

Two years later I was sitting in that chair in the surgery going under global anaesthetic. I was reassured that I'd be asleep for the entire procedure and wouldn't feel a thing.

Sure enough, I went to sleep, and woke up in exactly the same room.
I remember being surrounded by scientist types, some looking exactly like the anaesthetist and aide that had accompanied me into the room, but I knew that it wasn't really them. I don't remember their technobabble, but I do remember a golden robotic arm coming out of the wall with some vial in it that I knew would be used to impregnate me with some horrible monster. I screamed and screamed begging them not to, and in the end the arm retreated back into the wall.
I tried to get up from the chair, but was immediately pushed down by a strong arm.
Time seemed to freeze then. I attempted to get up multiple times only to be pushed back down by some unseen force. I couldn't summon the strength to do so. I was trapped in this chair for eternity.
It seemed like hours. I wasn't sure what was happening was real- I knew somehow that it wasn't, but it was so lucid. I eventually resigned myself to my fate, assuming I would be stuck here forever.
I kept lifting my arms and legs, wiggling them around, clicking my heels together, just to check. It felt completely real.

Some time later, I came to feeling utterly horrible. My mouth was numb.
"You had an allergic reaction to the valium. You were shaking. We were so worried about you, we couldn't complete the procedure; we could only remove one of your teeth."
I remember looking at my hand. I still wasn't sure whether this was real or still part of the nightmare.
"Is this real? Am I awake?" I slobbered in typical anaesthetic talk.
"Yes, you're awake now."
"I had a nightmare."
"A nightmare? Well, people who are allergic to valium usually have hallucinations. You're okay now."
I sat up. No force pushed me back down. I looked around the room for a little bit at all the concerned faces and the machinery which I'd spent the last eternity being forced to stare at and examining the reflections.
"You're going to be a little groggy from the anaesthetic."
Fuck that. I was walking. I got out of the chair and immediately fell to the floor.
I couldn't walk.
My granny came in, and she was very worried. I had to lean on my brother and summon the strength to walk to the car.
I felt completely helpless. I couldn't walk, I couldn't talk properly, I couldn't even open my mouth very far. And on the whole ride home I still wasn't sure whether I was still dreaming.

I had to get my other teeth out individually every week or so under local anaesthetic. The next time I went into the surgery, I was afraid it would happen all over again. And while the other procedures were trivial, I still felt worthless being unable to eat properly. I was depressed for weeks. And the pain from having your wisdom teeth out is horrifying. I spent hours curled up in my bed begging for the pain to stop.

I'll never forget how I felt in that nightmare. I don't know whether it was a hallucination, or what, but it seemed completely real to me. I was terrified at first, but in the end I gave up and figured I would just be there forever. It was the worst thing I've ever been through.

Length: I think it took a few days for me to accept I was in the real world.

Sounds bloody grim
When I had to have 3 wisdom teeth out all at once, they did it under general anaesthetic, so I was totally out all of the time. Woke up with a gob full of blood and bits of bone and teeth. Had to eat through a straw for a few days. Wasn't bad at all really, and it got me a week off work. Sorry to read about your horrific experience.
