I only mention that because during my very first ECT treatment I experienced anesthesia awareness at one point, which is rare (1 or 2 people in 10,000 or 0.1% or 0.2%). It's hard to know how big of a factor that was in some of my issues in the years right after. When I told the ECT nurse afterwards, it was taken very seriously. The anesthesiologist interviewed me at the hospital, apologized profusely, and promised that it would not happen again. It didn't. Just to clarify, it did not happen during my shock, but it was still frightening because my muscle relaxant hadn't yet worn off. I have had flashbacks of this event, though mostly in my night dreams.
