increasing acetylcholine levels

High levels of acetylcholine are linked with increased REM sleep. That may be the reason that the most potent lucid dreaming supplements either increase acetylcholine levels in the brain or stimulate the acetylchonic receptors.

But there are ways to increase the levels of this substance in the brain without the use of substances.

The german physican Dr. Joseph Zehentbauer investigated other ways of raising the brain levels of acetylcholine.

He lists following methods:

Active Imagining
Producing vivid internal images, he claims, will increase brain levels of Noradrenaline, Dopamine and Acetylcholine.
Active Imagining was invented by C.G. Jung as a form of therapy.
Zehentbauer uses this term as a generic name for every method which stimulates ones phantasy.

Mindful Awareness
Where you guide your awareness in your body influences your brain. If you guide your attention to your brain your acetylcholine and noradrenaline levels increase whereas attention to your body raises your endorphine levels.

Brainstorming
Just get into the flow of new ideas. The delicate state your brain is in when creating new ideas rises the acetylcholine levels as well.

Studying 
Of course: Acetylcholine is the neurotransmitter of memory. According to Dr. Zehentbauer the claim is true that intense learing makes your memory transmitter levels rise.

Some of this methods like active imagining suit better in the evening whereas studying or brainstorming are ideal for doing during a WBTB.

So there is an interesting field for new experiments.

Meditation and Lucid Dreaming

In a Study of 1992 by Jane Gackenbach discovered that regular practice of Meditation increases the frequency of Lucid Dreaming. In her Publication
Interhemispheric EEG coherence in REM sleep and meditation: The lucid dreaming connection she discovered that

[...]The emergence of consciousness in sleep (lucidity) is enhanced by the practice of meditation and is most likely to occur during the stage of sleep that shows interhemispheric balance in the alpha/theta range, REM
According to my experience I have more lucid dreams when I meditate often. Before I knew that lucid dreaming is a learnable skill I had occasionally had some lucid dreams in periods when I did a lot of meditation.

Unfortunately I don't know which kind of meditation increases the lucid dreaming frequency most. It would be also interesting to know what exactly causes the lucidity. Is it the increased alertness during the day which remains up to the REM-Phases? Or the relaxation like increased alpha waves?
There are a lot of different forms of meditation.
Osho introduced in his 'Book of secrets' on 1152 pages about 112 different forms of ancient indian meditation. There is a big chance that you will find one that fits.

The most popular techniques can be found in his book 'Meditation - the first and last freedom' which is much cheaper and shorter.
