I read a lot about RC’s but I don’t think I’ve ever read about linking RC’s into dreams. Basically what I got from reading is that just randomly do RC’s throughout the day and not actually linking them to a thought or sight of something.
Instead of just doing an RC every hour, how about conditioning yourself to THINK of doing an RC on a certain object or action(maybe thats what dreams signs are for but I’ve never read). In example, every time I see a light switch or look at a clock I should think “Oh! i should do an RC.” Instead of randomly doing them and possibly randomly doing them within a dream.
I only say this because I find myself thinking in my dreams. Never become lucid tho, only thought of this today.
