Dental surgery under general anaesthetic at age 10 (lots of local anaesthetics to have teeth pulled, too...I have stubborn teeth). Then nothing until age 37 when I had to have an emergency caesarean (c-section). I was awake for that. I had done months of listening to affirmations and practising deep relaxation so thankfully I was able to cope with it...it's hard to think about it in detail, though...remembering the sensations of scissors cutting me open, and being pulled as I was stitched up... I had to kind of actively dissociate myself from what I could feel. My brain was able to shift focus from that to being grateful that I was going to survive that pregnancy, haha.
