I agree with the idea that LDs are more intense when we let things be natural. I have had many experiences where I realize that I am dreaming and then I try hard to control myself instead of being plain old aware. One time--the entire dream world shattered like it was made of glass when I realized I wanted control and completion of desires. Another time, the world became scarred as my gaze passed over it and my desires grew and I started to grasp at things. And things DID become all cartoony and simplistic as one post mentioned before this.

I think this signifies something. From a interpretative point-of-view maybe this means that the dream world is a natural by-product (a side-effect) of stepping on the spiritual path to self-realization and that doing unnatural things that aren't related to self-realization will only mutate things. But that's another discussion.
