When my friend found himself walking around in a new place after a complete discontinuity in experience. Was this discontinuity entirely driven by the impairment of lasting memory formation? Seems possible to me. Problem is, I've never experienced this myself - only heard his story from a close friend (repeatedly) and similar stories from others. The stories could be unreliable - but they suggest that the self was offline and came back while the body was still performing complex externally awake actions. Seems p-zombie-like to me.
