北岛以北海深眠
[bĕi dăo yĭ bĕi hăi shēn mián]
'Deep Slumber Beyond the North Island's North' is an imaginative or dream-like description indicating a place far beyond what's normal or reachable (beyond the known, like north of a northern boundary). It can symbolize longing for a far-off, unreachable dream, escape, or peaceful rest in an unimaginable distant realm.
