Where is there confusion in a midsummer dream?

There is confusion throughout A Midsummer Night's Dream due to the mischievous actions of Puck, a fairy who serves Oberon, the king of the fairies. Oberon instructs Puck to put love potion in the eyes of Demetrius, so that he will love Helena instead of Hermia. However, Puck mistakenly anoints the eyes of Lysander, and as a result, Lysander falls in love with Helena, leaving Hermia heartbroken. This confusion is further compounded when Oberon decides to use the potion on Titania, the queen of the fairies, causing her to fall in love with Bottom, a weaver who has been transformed into a donkey by Puck. The subsequent interactions between the four lovers, Oberon, Titania, and Bottom create multiple layers of confusion and misunderstandings
