Itcametomeinadream is an experiment in web-based poetry, or "hyperpoetry" (a term coined by the site author).
Poems are written about a single word and submitted. Any mentions of that word in other poems automatically link there, and each poem is linked to the inspiration for the work (often an emotion or feeling).
Collecting poetry in this way provides a unique experience for readers, as they choose the words that are most appealing to them and follow their own path. Recurring words and themes will also become much more prominent, as many more works will link to them.
At any given time, there are a large number of "orphaned" poems, whose title is a word that has yet to be mentioned in another poem.
