The higher pitch for the entire sentence is another option in my Spanish, but indicates outrage.

The version where you hear it's supposed to be a question from the word "dijiste" is more of a request for information, like if your mom yelled something and you're not sure if she said "No me molestes" or "No te sorpreses" or something else that sounds vaguely similar or if she was actually yelling at a fly that was going on her nerves.

The sentence overall becomes more melodic, with the stressed syllables getting a higher pitch and more defined stress.
