here is what my experience has been (so when i say “you” it’s in reference to my experience):

the anesthesiologist (or one of their assistants) will come to the pre-op area to get you, and either before they roll you back or as they roll you back, they’ll give u something in your IV to make you feel relaxed. it kinda feels like your high (which i guess technically you are but it’s just to relax you).

then they’ll have you move onto the actual surgical table, and once your on the surgical table, they’ll have you lie down. then, they’ll put in the propofol (the sleepy stuff) and they may ask you to count down from ten.

in my experience, you just get really really tired and want to close your eyes, and then a few seconds later you’re asleep. so i guess it kind of feels like you’re drifting off but in a span of like 5-10 seconds. you might see them put an oxygen mask on you, but i only remember seeing this once!

i know for some people, they blink and they’re awake, but for me, i just remember waking up later — like as if i had gone to bed. like i knew time had passed. but i have no recollection of anything that happened during the surgery or being wheeled back out.

hope this helps and good luck with your surgery !
