Well that is not entirely correct. Daydreaming is fine, as long as you know you’re doing it 
it was calledLucid DayDreaming in another topic. Besides, Dazino’s pretty right, in order to be lucid you must be aware, so you will recognize if it’s a dream or not from the feeling and the (not so) subtle clues 
. And being aware can be done in daytime too, so you can start practicing right now 
Besides, what that “split from scribes’ topic” mean?
