CALD is created by Talon here : https://community.ld4all.com/t/cald-tutorial/28013
Baiscly i have created a character (nicklebrick), and every time i am lucid and in most ND i see him because he is my awesome friend. So what i posted earlier was about jsut creating something from scratch and making him a dream guide (CALD) and jsut let him form himself, and eventually he will become your DG if you can believe in him enough… just a guess, i have never actually tried it
