Keep speaking it's when you stop to think what to say that the images start disappearing. It's fine to go with the flow and describe from your imagination. Image streaming and talking out loud is one of those things that does get better if you just do it and keep talking. It might feel like you're making it up but the biggest mistake is to censor the information that comes to your mind. Remember to describe feeling sensations and sounds as well as visuals.
