Yes, but it is becoming less common.
Newer pumps allow the precise amount of hypnotic (sleeping drug) to be administered to keep the patient asleep.
Awareness sensors can also be used to approximately measure how awake the patient is.
Previously, it would have been the job of the anaesthetist to monitor signs from the patient and adjust the drug infusion rates.
It is very unlikely nowadays! Plus, hospitals are trying to do as many surgeries as possible with the person awake (but with a local anaesthetic that numbs the area) as this is safer and quicker for recovery. So no pain, and also no worry that you will wake up without the doctor noticing!
Yes, it happened in the past and it can happen if the things are not done in the correct way. But it is very rare and during the surgery there is always a doctor specialized in keeping the patient asleep; this doctor is called anesthetist.

Yes it can happen. But sometimes surgeries are done when the patient is awake… do you know nowadays some brain surgeries can be done using just local anaesthesia? there are not studies about whether is better to use general or local anaesthesia… it is a very interesting question, I might think about it the coming days
I don’t know a lot about this subject, so I was interested to read the others’ answers. I have heard that a lot of people who have major operations under a general anaesthetic suffer complications due to the anaesthetic rather than the surgery itself, so it’s desirable if possible to perform an operation using only a local anaesthetic or what they call twilight sedation (a light dose of general anaesthetic that means the patient isn’t fully unconscious, but isn’t really aware of the operation and doesn’t feel any pain or discomfort).
