What mood does this stanza from henry wadsworth longfellow’s “the tide rises, the tide falls” evoke in the reader

Here is the full stanza for this question:
Darkness settles on roofs and walls,
But the sea, the sea in the darkness calls:
The little waves, with their soft, white hands,
Efface the footprints in the sands,
And the tide rises, the tide falls.

The mood that this stanza evokes in the reader would be: a growing sense of anxiety
at first glance, we may not see the sense of anxiety from this stanza. But if we look closely, the author Describe the situation on the sea when the night fall, which could be very dangerous for anyone on it.
