How many types of Genjutsu are there?

In the Naruto series, Genjutsu is primarily categorized into three main types: Demonic Illusion (Magen), which manipulates the victim's senses; Dreaming (Yume no Jutsu), which traps the target in a dream-like state; and Cursed Technique (Noroi no Jutsu), which induces fear or paralysis. Additionally, Genjutsu can be classified based on the method of application, such as eye techniques or sound-based illusions. Overall, while there are various techniques and applications, the core types are rooted in sensory manipulation and psychological effects.
