What happens
Titania falls asleep in her flowery bower while her fairies sing her a lullaby. Oberon enters unseen and anoints her eyes with love-juice. Lysander and Hermia arrive, exhausted from the forest, and lie down to sleep nearby—but Lysander places himself at a distance to respect Hermia's modesty. Puck enters and, mistaking Lysander for Demetrius, anoints his eyes instead. Helena and Demetrius run through, with Helena desperately pursuing the man who scorns her. When Lysander wakes, he sees Helena and instantly falls in love with her, abandoning Hermia.
Why it matters
This scene is the hinge of the play's catastrophe. Oberon's plan to help Titania discover she's been wrong sets in motion a chain of errors that will devastate the lovers. The anointing of Titania's eyes is presented as almost benevolent—Oberon watches her sleep with pity, acknowledging the spell's power will make her 'mad with love.' But Puck's crucial mistake—anointing Lysander instead of Demetrius—transforms a scheme to teach Titania a lesson into a crisis that unmakes all four lovers' identities at once. The scene moves from romantic to chaotic in a single moment of magical misdirection.
The sleeping lovers' dialogue before Puck arrives reveals the play's central tension between desire and decorum. Lysander's attempt to bed down beside Hermia is framed as innocent devotion, but Hermia insists on distance, invoking 'human modesty' as the boundary between love and impropriety. Their tenderness is real—yet within moments, magic will destroy it entirely. When Lysander wakes and speaks of Helena, his language mirrors his earlier vows to Hermia word-for-word, proving that love in this play is not a choice rooted in the person loved, but a force that seizes the lover and rewrites his reason to justify whatever his eyes compel him to feel. The magic simply reveals love's true nature: irrational, violent, and utterly indifferent to the self.
Helena's entrance, pursued and scorned by Demetrius, provides tragic counterpoint. She is abject, begging for the cruelest scraps of attention, calling herself his 'spaniel' and offering to bear any humiliation for a glance. When Lysander suddenly adores her, she cannot believe it—she thinks she's being mocked. This moment plants the seed of her later suffering: she will spend the rest of the play convinced that both men are conspiring to torment her, unable to trust her own good fortune. The scene ends with four lovers utterly rearranged, none of them aware of the magic, all of them convinced their new loves are authentic discoveries of truth.
