Thanks for your question! Wet dreams usually happen when a guy has a sexually arousing dream during the REM (rapid eye movement) phase of sleep.  During this time, it’s natural to have an involuntary erection followed by the release of semen (ejaculation) = “wet dream”. There are no research studies that prove that sleeping nude increases or decreases a guy’s chances of having a wet dream. This is because everyone is different. What might increase one person’s chances, may not affect another person’s experience. Some people feel that friction or rubbing of clothing against a guy’s penis during sleep might cause a wet dream, while others think that being naked may cause them. It’s all individual. You may want to experiment and try sleeping with and without clothes to see if you notice a difference.
