Can gaming trigger unvoluntary muscle contractions during sleep?

I am curious cause my boyfriend played nfsu for 6 hours yesterday (!yes) and had weird contractions of his whole body/feet during sleep (1 e minute). he was unaware of them. is this some kind of sleep disorder or can video gaming cause these problems? cheers
Answer
As some one points out some sleep disorders are due to lack of enough vitamins, minerals and the other bodily requirements. i remember i had slept like a child when i was regularly taking some supplements. but your description makes me believe in what you suspect. our subconscious is a continuous stretch even while asleep. since no conscious mind to take control of the activities and no way subconscious control our wakeful like actions it gets expressed in some thing like what you described here. doctors do agree with such psychological conditions, however, nothing serious about that, if the reactions stops when your b/f stops playing games for enough time. try redirecting his attention to other things before sleep and you can observe if chance permits. if the same behavior is not observed then what you think is correct, else it must be some medical condition known to doctors/psychologists.
