How it's used
This term is used primarily in clinical or health contexts rather than casual conversation. While it describes a natural biological process, it carries a slightly clinical or embarrassing tone that makes it awkward to bring up in everyday social settings. It is often discussed when talking about puberty or sexual health.
Examples
Is this your first time having a nocturnal emission?

Common phrases
the phenomenon of nocturnal emission
Common mistake
Learners sometimes confuse this with general dreaming or nightmares because of the character 夢. It specifically refers to the physiological event of ejaculation during sleep, not just the content of a dream.
