O, then, I see Queen Mab hath been with you.
She is the fairies’ midwife, and she comes
In shape no bigger than an agate-stone...
And in this state she gallops night by night
Through lovers’ brains, and then they dream of love;
O’er ladies ‘ lips, who straight on kisses dream,
Which oft the angry Mab with blisters plagues,
Because their breaths with sweetmeats tainted are...
