Is it normal that i get urges to kill and laugh like a maniac

This is starting to get ridiculous and I've had enough of it. Sometimes on random occasions, mostly when I stay up all night, I get the urge to laugh like a maniac(which I do, and end up having to smack myself to stop)which instantly makes me hyper, and then I get the urge to kill someone (which I do not intend to do, EVER) Any solutions? I need an answer ASAP.
