Anyone do things better when they're not paying attention?

I'll often find myself doing something and not paying attention, completely in my own world in my head and then when I snap back to reality I'll have done it really well with no conscious thought, focus or even memory unless it's something I can look back on and revisit whatsoever.

Just now I was playing a game of FIFA against someone online and when I snapped back in to reality after the game being on for only a minute or two I'd score 3 goals. This is something I've always experienced and I'm not too sure why.I remember at school I'd often snap back into reality and read through my work and it'd be really good but after starting to focus on it or even realise I'm doing it it'd go back to standard stuff. It feels strange thinking about it now but it has always seemed normal to me.

I seem to excel in pretty much anything if I'm not focusing on it yet if I'm "there" rather than in my own head I'm quite average at everything.

Anyone experience something similar or have any idea why?
