The funny thing about blackouts is that most people assume that because they can't remember what happened that they were not conscious at the time. I think this is a fallacy.
You are aware of your actions during a blackout, you just can't remember them later. It is not like sleepwalking.
Does this make sense? I think it is a very misunderstood aspect of blackouts.....even the term is a little off....you aren't actually "in" a blackout, its just that later your memory of that time period is blacked out and you cannot recall it.
