Midazolam/Versed sedation seems pretty close to a p-zombie. You can have someone who seems completely awake, walking around and interacting normally, but if you ask them later they were completely unconscious from their own perspective. So self-reported consciousness isn't always accurate. And it also seems that consciousness is very closely tied to memory.
(I'm not arguing a particular position, but trying to figure out what to make of this. Also, this is based on what I've read, not personal experience.)

Were they unconscious, or are they now unable to remember what they did? I.e. amnesiac.
If you ask a deceased person about their life, you will find that they also will offer no evidence of a previous conscious experience. Life, apparently, resembles unconsciousness.
