Hi, I am a total newbie - this is my first response here! For me, when I visualize something, as per the PW instructions (or for anything) I imagine that the conversation is actually happening. So I don't actually imagine that my POI (my husband) is talking about something that we are doing or are going to DO - I have him tell me what I want him to tell me. In our case, he has to tell me he is sorry for what he did and ask me to take him back!
But let's say I wanted to visualize him lying next to me, I'd do that - then I visualize him asking me where we should go for coffee, the way he has a million times - "left or right?" (referring to which coffee shop). I only visualize (and see/hear/feel in my mind) things that are completely realistic.
Does that help?
