The scene is almost too ordinary to disturb: a girl comes home on a summer afternoon, finds her mother asleep in a chair, and leaves again. Walter de la Mare was drawn to the border between sleep and waking, and here he makes that border a quiet domestic room. The central drama is not what happens, but what Ann sees: in the silence of the house her mother ceases to look entirely human and becomes “half unreal,” a figure at the edge of dream. The poem suggests that sleep, however familiar, can make a loved face strange, and that a child may sense this more sharply than adults do.
The verse works like a hush. Its four-line rhyme groups follow an ABCB pattern and alternate longer four-beat lines with shorter three-beat lines, a ballad measure that feels like a whispered rhyme. The short second and fourth lines drop away softly: “She felt that she must creep, / … It seemed a house of sleep.” That falling rhythm imitates the held breath of someone trying not to wake a sleeper. Punctuation slows the lines too; dashes and semicolons make the poem hesitate, as Ann herself hesitates. The repeated phrase “Fast—fast asleep” drags out the moment, while “quite, quite still” turns the girl’s own posture into another kind of sleep.
De la Mare builds the uncanny effect through precise visual details rather than through any plot twist. The house is “clear” and “cool,” with alliteration that makes the air itself seem rinsed and thin. Sleep is not dark here; it is a “pale light” that “calmly lit” the mother’s features. That gentle light smooths away “every trouble,” leaving the face fair and untroubled, but the smoothing is double-edged: it erases the lines and tensions that made the face an individual. The mother’s hands are “loose-folded,” her face “small” and “unconscious,” so she becomes almost a waxwork or a painted image. The odd phrase “half unreal to be” catches the child’s perception exactly: the mother is present in body, yet not quite there.
The most unsettling idea arrives as the poem turns toward its close. Though the mother’s lids are “fast-sealed,” her gaze seems to rest on Ann. It is an impossible look, coming from beneath closed eyes, and it collapses the distance between watcher and watched. Ann stands “quite, quite still,” but the sleeping mother appears both unaware and strangely observant. Her breast still moves with breath, a sign of life, yet the rest of her body is “saturate with sleep,” soaked through by another state. Here sleep becomes a substance, almost a presence, that has taken possession of the mother.
That is why Ann’s reaction feels proportionate rather than childish. The dread that “stole over her” is “cloudlike”—diffuse, atmospheric, not attached to any visible threat. It comes from the transformation of the familiar, not from an intruder. Ann retreats on “stealthy, mouselike feet,” becoming tiny and wary in a house that now seems larger and stranger than when she entered. The final word, “again,” closes the poem as a loop: Ann has slipped in and slipped out, and nothing has happened except a shift in perception. Yet that shift is the poem’s subject. In a few quiet lines, De la Mare makes the ordinary act of finding someone asleep feel like a glimpse of another world wearing the face of home.
