Shakespeare's scenes are not meant to sound like real dialogue.
Explanation:
Theater in the time of Shakespeare was yet to focus on the realistic aspect of dialogue. It was often lyrical, musical and indirect.
Shakespeare himself used verse extensively in his plays resorting to prose very sparingly in the tragedies and a little more in the comedies and the problem plays.
The dialogue is not supposed to be realistic in content but in theme as it is what someone might say in a situation, but it is highly ornamented and loaded in Shakespearean double entendres and purposes.
