How is A Midsummer Night's Dream like a dream?

Technically yes, have you seen the play? Well, Lysander and Hermia are meant to be a couple and then there is Helena and Demetrius who aren't together. Puk, a fairy puts the juice of a flower onto the eyes of Demetrius and Lysander who both fall in love with Helena, because the juice of the flower makes the person fall in love with the first person they see. It is like a dream because it is very magical and the lovers kind of switch around.
