Yelling during sleep can present in several different ways. Understanding the type can help identify whether it's benign or tied to a specific sleep disorder:

Night terrors: Involve sudden arousal, yelling, and panic, mostly in children.

Sleep talking (somniloquy): Milder vocalizations that may escalate to yelling.
Sleepwalking (somnambulism): Can involve vocal outbursts while partially awake.
