What is the difference between ghusl for janabah and ghusl for a wet dream, and what is the method for each?

Janabah occurs when semen is discharged with desire (whether through a wet dream or otherwise), or through sexual intercourse, even without ejaculation. Janabah is described as a state of ritual impurity due to seminal emission or the penetration of theian, and there are two forms of ghusl (ritual bath) for it: a sufficient one, and a complete, sunnah-prescribed one.
