Why does Bottom constantly break character to talk to the audience

William shakespeare wrote many plays and comedies, "A Midsummer Nights Dream" illustrates the Duke of Athens' marriage with a former Queen of the Amazons and also embraces a group of amateur actors called "The Mechanicals", these ones are controlled by the fairies in the forest where the events occur; Nick Bottom is a humorous character providing comic relief across the play; part of it is talking to the audience explaining the plot due it has many mistakes that need clarification to avoid the audience to be confused, thus Bottom tries to disguise those mistakes by talking to the audience,

"He thinks they don't understand how theater works".

Bottom breaks character and says to the duke that really thisbe her cue, but she'll be there soon. Sure enough, thisbe comes up, lamenting that the wall separates her and pyramus. Pyramus recites his lines, which are all messed up.
