I don't know what they are called but I have the same problems. A lot, it's like you become detached from what you are doing. It's a memory lapse but it feels different. Like your thinking brain cuts out. The food thing I do as well, or sometimes I'll drive to the wrong place and kick back in when I get stopped and think why the hell did I end up here.

I think some of it is concentrating and fatigue coming together to mess you up. I have to effort myself to stay aware. This probably isn't that helpful but know that what you say is something I deal with a lot too! Some days not at all some days are like an out of body experience all day
