So, I was wondering how does meditation affect lucid dreaming, if it does so in a direct or indirect way, and if anyone took the time to analyse and post any results. I'm not refering to the obvious indirect advantages it provides, like improvement on clearing the mind and more easily focus on a mantra/ADA/WILD or decrease on the "mental noise" we usually possess (random thoughts during the day).

This is the main idea I've gathered from several sources around:

- In deep meditation, people seem to enter such state that can somewhat relate to the deep sleep stage. The regular and constant breathing, the abstraction of the mind regarding physical and external stimulus and the relaxed position of the body can be observed in both sleep and meditation (assuming naturally the differences in physiological characteristics of sleep vs awake state).

I also heard that performing meditation can reduce the amount of time you stay in deep sleep, thus entering in REM stage more quickly.

I found no evidences or anyone commenting on these things, so I'd like to hear some input about whether meditation can decrease the average time of deep sleep. Many oneironauts report that meditating a bit before focusing on your mantra (for example during WBTBs) helps, but is this only in the "mind clearance" department?
