Drug hallucinations during sedative anesthesia? Has anyone experienced this?? (experiences)

When I had eye surgery, what did I do under minimal anesthesia for 5 minutes? Jaewoo was put under sedative anesthesia.
 He was put under sedative anesthesia three or four times? It took 3 hours and 30 minutes for all the surgeries that can be done on the eyes.
 So, I underwent very short sedative anesthesia several times, but
 this was my first experience.
 The moment I was sedated, I was suddenly sucked into time and space, and
 I could see sounds in front of my eyes. There is no way to express it as I was riding those sounds(?). All I could say was the feeling that I was flying while riding those sounds. I can't explain it.
 The things I see in front of me magnify like crazy and I get sucked into it, like a doctor or a nurse. I can clearly hear this speaking voice, but as the sound is visualized, I keep seeing things like time and space being distorted right in front of me. But when I first experience this, I think, “Wow, what is this?” It definitely doesn’t seem real, but it’s too clear to be a dream, but when does this really happen when I wake up? At the time, I couldn't really distinguish it from reality, but after repeating this two or three times, I was able to clearly recognize that I was under sedation, that this was a hallucination, right??
 I can see the doctor's hand, and it suddenly twists 34, 60, and 90 degrees, and the sound of the surgery gets louder, and then I see the sound in front of me ;;
 Oh, I don't know how to explain this in words ㅡㅡ But it's really so strange. Has anyone experienced this?
 I have had several surgeries and been under anesthesia dozens of times, but this is my first experience like this;;
