I wonder if Titania be awaked;
Then, what it was that next came in her eye,
Which she must dote on in extremity.
How now, mad spirit?
[Enter Puck]
What night-rule now about this haunted grove?

– William Shakespeare

A Midsummer Night’s Dream, Act 3, Scene 2. Oberon asks Puck what mayhem is in this haunted grove. He is wondering if Titania has wakened up from her sleep and if the love potion has worked on her so that she has fallen in love with a beast.
