What happens when someone blacks out?

Question

I've been a little curious for a while now.

When someone blacks out, do they just suddenly forget what happened from one moment to the next?

Or are they like on 'autopilot' during the time that they black out?

Answer 1

Many different things can happen.  I once blacked out while drinking too much and I'm pretty sure I had a good time before I passed out, but do not remember what happened.  You sort of remember feelings and emotions but not specific events.
