If I understand your question correctly, you are referring to the fact that the imagery associated with nature is far more important than the speaker's intent in the poem "I Wandered as Lonely as a Cloud" by Wordsworth. If this is what you are saying, then I agree with you.
What Wordsworth is offering is a place for readers to find the same thing as he has in nature. Wordsworth has found in nature a place for him to reflect:
In vacant or in a 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.
Therefore, the intent of the poem is to relay the message that all one needs to find is a place in nature that fills one with substantial emotion so as to pull them out of any depressive or angry state. Nature has created such an impact on Wordsworth that he is able to recall the image of the field of flowers whenever he needs cheering. This seems to be, by far, the more important message of the poem.
It is not the fact that Wordsworth, himself, is able to replay the images burned by nature on his 'inward eye'; instead, it is the fact that nature has the power to move all people so that they can use it to bring out more positive feelings.
