Here's the thing, I never assumed it as a near death experience at first, after I woke up I thought I had a brief moment of awareness and saw a nurse. So, when I was walking around I started looking for her, asked around other nurses about her. They could not fit a name to the description, I was in the hospital a week before being discharged and not a sign. Like not even in passing someone that might have been her.

It was only when the advice started bearing fruit that I really came to accept it as, best word fitting is guardian angel (even though the being had no real "angelic" features).
