Does anyone know what is the allusion of Walt Whitman's poem "I dremed in a dream" Thanks for the help.
Is this one

I dream’d in a dream, I saw a city invincible to the
attacks of the whole of the rest of the earth;
I dream’d that was the new City of Friends;
Nothing was greater there than the quality of robust
love—it led the rest;
It was seen every hour in the actions of the men of
that city,
And in all their looks and words.​
