Pt. 1 & Pt. 2 (opinionized)
Shakespeare's plays are still well known, read, and liked today, because the plays speak to common themes and character types that are still relevant to today's society. The language is outdated but, his connection with humanity at a base level was strong, and even now people have not fundamentally changed since his time.
The dreams in the play symbolize the reality and how they were switched around with, lovers who they didn't really like/love.
