LCD in my experience allows you to take note of things that have fallen outside of your perception filters. Such as squeaky door that you said you would oil but you delayed doing so and eventually it just became part of the door and you stopped noticing. I attribute any creativity to this weird fresh perspective. You could even argue that altered states always can give new perspective by virtue of what they are.
