Do you think Innisfree is only a place, or a state of mind? Does the poet actually miss the place of his boyhood days?

Innisfree is poet’s boyhood scare and it also represents his state of mind. The poet wishes to escape to Innisfree because it is much more peaceful than where he is residing now−the city. Innisfree is representation of what the poet considers an ideally perfect place to live, which is deprived of the restless humdrum of his life.
Yes, the poet actually misses the place of his boyhood days. Even when he is away from Innisfree, he remembers the sound of the lake water washing the shore.
