I know this is a stupid question.I was just wondering if anyone knows why you can control your urine and bowels when sleeping,but not gas?

Not a stupid question at all. For both urine and bowels there is storage space in your body to hold them till the next visit to the toilet.
For gas there is no storage, as it has to be removed as soon as possible.
All you can do to reduce gas production is make sure you have the proper intestine bacterial mixture. There are medicines for that.
