I am on day 17 of the SEP, and I am confused about the dialogue technique. It says "Remember for this exercise you can choose any person, body part or entity." I understand that you can choose a person and then you can write what you want, then you can imagine what they say and you write that down. How do you have a dialogue with a body part or entity though? A body part or entity can't talk or have feelings! Or am I meant to imagine they can talk? Thanks!
