Hello, thanks for the query. First you need to relax & not to think of nocturnal emissions or night falls as pathologic or some form of disease. Nocturnal emissions usually occur in unmarried males in response to dreams with sexual content, thoughts etc. They are simply manifestations of mind's desire to have a fruitful sexual intercourse. As you might be aware that masturbation or sexual intercourse causes release of endorphins or relaxing chemicals in brain which causes a sense of satisfaction & sleepiness/sluggishness. Hence, masturbation is considered as a taboo in society & in effect having night falls is also considered to be a sign of disease or weakness. Relax & dont worry. Do revert back if you need further help.
