Fairies and Cupids intervene in our love lives causing chaos that we believe are only dreams.
Demetrius and Lysander fall in love with Helena in their dreams.
Lysander and Hermia are going to run away together until Lysander is sprinkled with fairy dust and now loves Helena.
Puck has messed up and he corrects his mistake so Demetrius and Helena can be together.
So at first Demetrius is running from Helena and then they are in love.
What if the dream was real and no one ever made it because cupid crossed his bows?
