How it's used

Refers specifically to the mental space where memories, thoughts, or images reside. It is almost always used with the preposition 喺 or 入面 to indicate where something is happening. Unlike 心, which often deals with feelings or intentions, 腦海 focuses on cognitive processes like recall or imagination.

Common mistake

Avoid using it as a direct synonym for brain as a physical organ, which is 腦. It is strictly a metaphorical space for mental activity.
