The Lowest Rated Player Can Make Me All Nerves

Such low rated players lower than me can upset me and make me nervous. Chess demand a great deal of concentration and unless a great champion can play in their sleep a lack of concentration can be an upset for the better player. Show me a player than can move in their sleep I know some players can play blind folded. That's incredible. I'm about to crash(do no concentration but rest and sleep if possible).
