Meaning

To feel uneasy, get a bad vibe, sense that something is off — a gut-level inner unrest.

ざわつく comes from the onomatopoeia ざわざわ (zawazawa), which describes a rustling or murmuring sound — like a crowd growing restless. The verb form ざわつく captures the feeling of inner unease, as if your instincts are picking up on something wrong. Popularised by the manga 'Kaiji' where the iconic ざわ...ざわ... sound effect represents mounting tension. 心がざわつく (kokoro ga zawatsuku) = my heart feels uneasy.

Examples

2. なんか嫌な予感がしてざわつく。 I've got a bad feeling about something, it's making me uneasy.
