Insomnia is usually described as a lack of sleep, rest or peace. Erin W's untitled sonnet, marked only by three asterisks, treats it as a surplus: too much memory, too many imagined lives, too much night. The speaker lies awake while "flickering / Lives of might-have-beens" drift past. The central idea is that sleeplessness is not an empty state but a crowded, circular haunting, and the poem hints that the sufferer helps to build it.
The most striking structural fact is that the poem is a single sentence. It has commas and a parenthesis, but no full stop until the final line. Nothing is allowed to finish, so the reader, like the speaker, never gets a place to rest. Enjambment drives this. Lines end on hanging words ("claw at," "draw at," "flickering," "sickening"), and the sense tips over the edge into "Air," "Lives," "Odds," "Bends." The rhyme scheme is the Shakespearean one (abab cdcd efef gg), but the opening quatrain is unsteady. Its rhymes are trailing, unstressed pairs, and its lines run a syllable or two long. From the fifth line on, the verse settles into a tighter, mostly iambic pentameter, as if the speaker, having thrashed about, falls into the grim rhythm of the loop.
Water supplies the dominant imagery. The speaker "claw[s] at / Air" and "gasp[s]," then drifts through "shifting currents" toward a stream, so insomnia becomes a kind of drowning. The "sickening / Bends" work on two levels. They are bends in a river, but the word also recalls the diving sickness, and the poem's language of gasping and pressure makes that reading hard to ignore. The stream also echoes the old idea, often credited to Heraclitus, that you cannot step into the same river twice. Here the idea is turned upside down. The speaker keeps "stepping in that stream / And stepping in that stream again, again," and the river will not change. The currents shift, but the same bend returns "against your will." The poem even rhymes "stream" with "stream," a formal version of the loop: the rhyme promises something new and delivers the same word.
The middle of the poem contains its subtlest moment. The "thousand pointless lives of men" are "your own if you will only own / Them so." The pun on "own" suggests that these regrets and alternatives become yours by acceptance, and so perhaps by choice. The parenthesis also arrives where a Shakespearean sonnet usually turns, around line nine. For a moment the speaker seems to have some power, but the sentence rolls on and the night grows "thick / With living and reliving." The shift into "you" matters too. The poem never says "I." It addresses a general sufferer, which pulls the reader onto the mattress alongside the speaker.
The ending shows the poem's craft most clearly. The speaker is "prone / Beneath the weight," lying flat yet crushed, and can only "flail and burn and ache." The repeated "and" piles the verbs up. Then the final line strips them back to four participles, "Reaching, dreaming, praying, breathing," each smaller than the last, until the whole struggle shrinks to one word, "Wake." The word is genuinely ambiguous. It could be a plea to be pulled out of this half-dream, a wish for morning to come, or a command the speaker gives to a mind that won't switch off. In a poem so full of water, "wake" might also suggest the trail left behind a moving vessel, though that is a reading rather than something the text insists on. The irony is that someone "sick / For sleep" ends on a word meaning its opposite.
That irony is where the sonnet earns its place. The couplet "ache / Wake" gives the rhyming closure the form promises, but it brings no relief. The neatness of the form sits against the mess of the experience, and the clash is the point. A fourteen-line poem can feel like an entire night because the writing makes the reader work through a single unbroken breath, repeating phrases and going nowhere. Insomnia is a very common experience, and the poem makes it felt rather than merely described.
