I'd hate to wake up whilst supposedly under general anaesthetic - that must have been terrifying.
I was 5, and my mother had said that we were going to get ice cream. But instead, from my 5-year old perspective, we pulled up outside a large white building and inside, two guys in white separated me from my mother. I remember being terrified right then, and my mom wouldn't look at me or talk to me, then they whipped out this gigantic needle (an IV line). I threw the biggest fight my little 5-year old self could manage, which lasted about 45 seconds before they had me pinned down. I remember hiding my hand in my mouth, thinking they wouldn't be able to get to it.
I lost, of course, and they knocked me under.
I woke up completely unable to move. I could hear the doctor talking with my mom, and with all the force and all the strength in my little body, I cracked my eye open just a sliver, and I could see them peering down at me, discussing me like I wasn't there. I still can't decide which was worse - not being able to move but being fully conscious, or the betrayal of "Let's go get ice cream..." and having my mother be in on it.
I should mention that as an adult, I realized that my mother clearly had a case of Munchausen by proxy. There was nothing wrong with me, that time or for any other doctor's visit. But she liked the attention, even reveled in it.
A few minutes later, a nurse or a tech must have noticed my eye was open, because I remember them saying, "Fuck, she's awake." then everything going dark again.
Strangely, I don't remember anything else from that day, or the days after. But I bet I never got that ice cream.
And my mother never got my trust back.
