Read "i wandered lonely as a cloud" and answer the question.

[1] i wandered lonely as a cloud
that floats on high o'er vales and hills,
when all at once i saw a crowd,
a host, of golden daffodils;
[5] beside the lake, beneath the trees,
fluttering and dancing in the breeze.

continuous as the stars that shine
and twinkle on the milky way,
they stretched in never-ending line
[10] along the margin of a bay:
ten thousand saw i at a glance,
tossing their heads in sprightly dance.

the waves beside them danced; but they
out-did the sparkling waves in glee:
[15] a poet could not but be gay,
in such a jocund company:
i gazed—and gazed—but little thought
what wealth the show to me had brought:

for oft, when on my couch i lie
[20] in vacant or in pensive mood,
they flash upon that inward eye
which is the bliss of solitude;
and then my heart with pleasure fills,
and dances with the daffodils.

what happens in the third stanza?

the poet imagines seeing countless stars, waves, and flowers.
the poet reflects on the day that his sadness was very severe.
the poet sees the waves and watches the daffodils with awe.
the poet witnesses many natural wonders in the sky and on land.
