That's a good question. I don't know, I just know that they will get hit with all those messages as soon as their guard is let down. You don't necessarily have to visualise the cloud "bursting", it will burst when they're not resistant. Either way - it always reaches them.
I loved imagining the cloud bursting over a guy's head when I re-read the book. It was hilarious to picture. I think I was so impatient reading it the first time and also doing Veronica's challenge (which I found invaluable to finding myself again) and scripting, and videos, and long visualizations combined with PW/BWD that I missed more than I realized in the books. Right now, I'm only using Lanie's techniques. I have so much more time on my hands, in a good way. 😆.
