I had something like this happen in one of the surgeries that I’ve had. I had consciousness and sensation but couldn’t move or open my eyes. Luckily it was before they had made an incision, and I began to feel very panicked. I could hear the operating team talking and feel them preparing the area by wiping down my skin. It was a very ‘locked inside’ feeling.

Then I heard one of them (the anesthesiologist I believe) mention that my heart rate was going up. They mentioned something about administering more of something, and I went out completely. So it was handled well by that medical team, and I just had a close call. Just know that you can use your emotional response to signal the need for more anesthetic.
