What is the ruling on a wet dream and waking up to wetness on clothes, and is it forbidden?

Wet dreams are a natural discharge of a person's sexual energy and are not blameworthy. The proof of this is that the pen is lifted from the sleeper, and it is made a sign of puberty, and the Prophet, peace and blessings be upon him, affirmed the necessity of ghusl for a woman if she has a wet dream and sees fluid.
