So me thinks.
And I have found Demetrius like a jewel,
Mine own and not mine own.
– William Shakespeare
A Midsummer Night’s Dream, Act 4, Scene 1. Helena agrees with Hermia that "everything seems double" after waking up in the woods. Using a simile she describes Demetrius as a "jewel," but she is unsure of whether his love for her is real or an illusion. In fact he is still under the spell of the fairy love juice.
