something out of a fairytale

I see Queen Mab hath been with you.
She is the fairies' midwife, and she comes
In shape no bigger than an agate-stone
On the fore-finger of an alderman,
Drawn with a team of little atomies
Athwart men's noses as they lie asleep;
Her wagon-spokes made of long spiders' legs,
The cover of the wings of grasshoppers,
The traces of the smallest spider's web,
The collars of the moonshine's watery beams,
Her whip of cricket's bone, the lash of film,
Her wagoner a small grey-coated gnat,
Not so big as a round little worm
Prick'd from the lazy finger of a maid;
Her chariot is an empty hazel-nut
Made by the joiner squirrel or old grub,
And in this state she gallops night by night
Through lovers' brains, and then they dream of love;

This is she
