回忆逆流成河淹没你我
[huí yì nì liú chéng hé yān méi nĭ wŏ]
'Memories Flow Backwards into a River Submerging Us.' This represents drowning in overwhelming flashbacks - memories come back so forcefully, creating strong streams, even floods that drown oneself, usually associated with sadness or being submerged in past emotions. Here 'us' adds another layer of shared history.
