Karen Bassey's "In My Head" begins with a split screen. On one side, "everyone else smiled"; on the other, a speaker who "cried" and, in a striking figure, "died" while listening to her own heartbeat. Nothing is said about when or why the poem was written, so the speaker is best treated as a voice on the page. What the poem offers is a portrait of isolation so complete that it becomes a sound, one that only the speaker can hear.
The opening couplet is the poem's only clean rhyme: "cried" and "died." The pairing is blunt and almost nursery-simple, which makes the claim feel flat and final. Dying here is most plausibly figurative, a sense of the self going out while the body carries on, and the heartbeat she listens to is a nice irony, since it is evidence of life that she experiences as the opposite. After this neat start the poem abandons rhyme altogether, as if the pattern, like the smiling crowd, belongs to a world she can no longer join.
What follows is a run of clipped lines built on repetition: "Now I feel nothing / Speak nothing / Hear nothing." The word "nothing" becomes a drumbeat, and each line removes another ability, first feeling, then speech, then hearing. But the list ends with an exception: "Hear nothing but the sound in my head." The numbness is not total, because something fills the space. "Nothing" then changes meaning. In "To others it's nothing," it means that the sound does not exist, or does not matter. Her private reality is invisible to everyone around her, and the poem's quiet anger lies in that dismissal.
The most intriguing line is "To my peers it's the demon speaking." It is ambiguous. It could mean that her peers name the sound a demon, or that this is how others explain her behaviour. Either way, the "demon" is a label handed to her from outside, a way of turning her experience into something dramatic and frightening rather than something to be listened to. Her own word for it is far plainer: "the sound of loneliness."
The poem is full of contradictions, and they are its real engine. The sound is one she "yearn[s] for / Yet find[s] so unbearable." She wants it and cannot stand it, which is a recognisable trap, since a thing that is both comfort and torment is hard to escape. It makes her do "things unthinkable," a phrase the poem deliberately leaves unexplained. Withholding detail here is effective, because the reader's imagination supplies something worse than a specific example could, and the speaker's reluctance to name it suggests shame or secrecy. Another tension lies in time. She says "Now I feel nothing," implying a change, yet the sound is "the only sound I've ever heard," implying it was always there. The loneliness may not have arrived with the crying; it may simply have become impossible to ignore.
Structurally, the poem lengthens as it goes. The short, stabbing lines in the middle give way to the final sentence, which stretches across the whole last line: "The only sound that listens and hears at the same time but never speaks." It has no full stop, like the rest of the poem, so it ends by trailing off rather than closing. It also personifies the sound as a kind of companion that listens and hears, but the final phrase, "never speaks," undoes the comfort. This companion offers attention without response, which is exactly the shape of loneliness. A voice that never answers is an exact image for being surrounded by people yet unheard.
The poem's significance lies in this honesty and economy. It does not explain or resolve the speaker's pain, and it offers no hopeful turn. Instead, in a handful of plain words, it shows how a person can look fine to everyone ("everyone else smiled") while an entire inner world goes unseen. For a reader her own age, the value may be recognition: the poem says that such a feeling can be put into words, even when the person feeling it believes nobody is listening.
