Paging Dr McSteamy

Had to have day surgery on Friday (and no, I wasn't thrilled about going under on Friday the 13th), and I have to say anesthesia is so bizarre to me. I was out for maybe 20 minutes, and have no memory of going into the operating room or much else after saying goodbye to my mom. Plus hours later I found a sticky EKG patch (I'm sure there is a fancy term for this, but I don't know what it is) on my boob and another one on my back - AND a Band-Aid on my arm where I apparently got a shot (?). And I remember NONE of this. What exactly goes on in there during those 15-20 minutes? The world may never know.
