If you spoke angrily or wearily, this may show how you are feeling about something or someone.
If you are nervous before your speech, there is something you need to say or some information you need to impart but feel apprehensive about doing so. Pay attention also to the way in which your speech was received.
If you were cheered and clapped, you feel confident and upbeat, but if you were booed and jeered, you feel uncertain and lacking in confidence.
If close friends or family were in the audience applauding, you are feeling supported or appreciated by them.
If you listen to a speech by someone else, were they saying anything that might be relevant to you in waking life? If the speaker was famous, this might be wish-fulfillment but also might reflect concern with an issue or feeling that they represent to you.
