According to this excerpt from "i wandered lonely as a cloud" by william wordsworth, what does the speaker do when he is in a reflective mood?

the waves beside them danced, but they
out-did the sparkling waves in glee:
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
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.

he gets melancholy about his life situation.
he thinks of the scene described in the poem.
he reads to escape from the din of city life.
he writes as a release from his worries and fears.
