Answer 1

So, often when our speaker gets in these downer moods, the image of the daffodils "flashes" through his mind. The "inward eye" expresses what Wordsworth felt to be a deeper, truer spiritual vision. A person cannot share his or her own spiritual vision completely with others, and so it is a form of "solitude."
