Is "Kubla Khan" a fragmented poem?

I find your question highly insightful, because on the one
hand this poem seems to represent a highly vivid yet incomprehensible dream which really
defies explanation. Thus one view to take when studying this poem would be to argue that
it really presents us with a series of fragments of the dream that Coleridge famously
had and then couldn't remember. However, some critics would argue that in spite of this
apparent fragmentary nature of the poem, there exists an underlying unity of purpose and
theme that clearly shows the fragments work together as a whole and provides a structure
linking them in to each other.

It is possible therefore to
view this mysterious poem as a poem about the creation of poems. In fact, the poem
itself has been created from air - with words - to give us vivid images and a new way of
looking at creativity and the imagination. This poem then represents a celebration of
the imagination by focussing on what Kubla Khan built, but it also reflects the danger
of unbridled imagination, as summed up in the "tumult" that exists outside of the
imagination's "pleasure-dome". Certainly for me a key passage that seems to sum up this
theme and the desire and frustration of the author to be creative is the final part of
the poem:

And
all who heard should see them there,

And all should cry,
Beware! Beware!

His flashing eyes, his floating
hair!

Weave a circle round him
thrice,

And close your eyes with holy
dread,

For he on honeydew hat
fed,

And drunk the milk of
paradise.

The act of creation
achieved by the author in building the "domes in air" would make him feared and people
would regard him with awe, much in the same way that true poets who are able to harness
their imagination are both feared and respected.
