棺材里的死人睁开了眼睛
[guān cái lĭ de sĭ rén zhēng kāi le yăn jīng]
The literal translation means 'the dead person in the coffin opened his eyes'. It's rather dark and eerie. Possibly reflecting on shocking awakenings, unexpected events or a dramatic turnaround situation from what was once presumed dead or over.
