A Midsummer Night’s Dream

How does it apply to Bottom, Titania, and the 4 lovers?

This is my theme for my MSND essay, btw. 

As for Titania, her experience seemed to make her appreciate Oberon more than she did and realize that their quarreling over the boy as ridiculous and silly.

The four lovers' troubles are all solved through the fairies' meddling, despite the mess that Puck intially makes.  Lysander and Hermia don't have to worry anymore about dealing with trying to be kept apart.  Their love, after the mess is straightened out, is given her father's and Theseus's blessing.  This, undoubtedly, makes them realize how truly blessed and lucky they are to be together.  As for Demetrius and Helena, Demetrius finally realizes that he has been obsessing over the wrong woman.  Helena is much more suited to him.
