Why is Egeus disturbed? (in the beginning of the play)
Egeus is angry ("full of vexation") because Hermia is not cooperating with him on his choice of husband for her. He wants her to marry Demetrius, but she wants to marry Lysander. Egeus blames Lysander for "bewitching" Hermia and asks Theseus to enforce the law that requires Hermia to obey him. He can go so far to have her killed for disobedience or can send her to a nunnery. There doesn't appear to be an option for Hermia and Lysander to be together, which prompts their running off which propels the rest of the play!
