Insanity?

unless you were hurting yourself, i'd call that pretty funny. not laughing at you, but i just laugh when other people are laughing. it's cool cause i don't usually get as good a laugh. it's simply spreading laughter. so you spread a little laughter...at least to those of us with the right appreciation of this kind of thing. and if you're insane, that's okay too. as long as it's hamrless, random and unusually lengthy bursts of laughing and joy then at least it's a cool kind of insane.

Maybe, maybe not. I think you should check it out with a doctor, because it just might be a random outbreak then that most people have in their lives. I honestly don't think your insane but check it out haah. Good luck :)

Probably not. Everyone has weird fits of laughter/tears sometimes. Sometimes they are completely inexplicable. Unless this is a habitual occurrence, I wouldn't worry at all!

I don't think so but if your are very concerned than you should talk to a parent and get there opinion. But you were probably just having a random fit of laughter people get sometimes unless this happens on a regular basis
