The time and the place in which A Midsummer Night's Dream is set are entirely appropriate for an exploration of the theme of order vs disorder.
The play takes place in midsummer, or the Summer Solstice, a time of year when, according to tradition, the natural order of things is briefly suspended as men and women engage in feasting, revelry, and debauchery.
The bulk of the action takes place in a forest, where magic and enchantment reign. It says a lot that it is only there that Hermia and Lysander can feel free from the stifling conventions of the Athenian court. They can only truly be together in a disordered environment where all the traditional conventions no longer apply.
The contrast with Athens could not be greater. If the forest represents disorder, then the court of Duke Theseus represents order, stability, and a firm adherence to protocol. In Theseus's world, there is no place for enchantment and no place for people to do their own thing. In Athens, his word is law, and if he orders that Hermia shall not wed Lysander, then that's that.
In the forest, there is an order of sorts, but it can be upended at any time due to the use of magic. Even royalty in this part of the world habitually resort to magic to get what they want, such as Oberon's ordering Puck to put a spell on his queen Titania.
As a consequence, Titania falls in love with Nick Bottom, which is about as blatant a violation of the natural order of things as it's possible to get. The queen of the fairies falling in love with a humble weaver is the kind of thing that could only happen with the assistance of magic and could only take place in the enchanted forest. One certainly can't imagine such a thing happening in the ordered society of Athens under Duke Theseus.
