I was warned about that before I went into surgery last December. Apparently the doctor had experience with at least on patient knowing everything that had happened.
The only weird thing that I had happen was remember a man (the doctor?) and a woman discussing a "hanging" that was shown on the Internet that had happened that morning, and did she see it and she said that she had not but that she had only saw what was on the news.
Later in my room I asked the nurse if there was a male nurse working and told her of the conversation that I heard. She figured it was when I was coming out of the anesthesia. Very weird experience! Almost like eavesdropping!
