Hypnosis and Lucid Dreaming

The word Hypnosis derived from Greek and is named after Hypnos, the god of sleep. During an altered state of consciousness, the hypnotic trance the hypnotized person is open to accept different suggestions.
Hypnosis is applied for different purposes as overcoming tobacco addiction, improving mood during depression, improving the sex life or raising self esteem.

But does it really work? 
You may buy a lot of hypnosis CDs, MP3s or attend a session at a skilled hypnotist.
The CDs are often blatantly advertised and promise to cure everything. But are there valid proofs?

In his book 'Psychology: Core Concepts' Philip G. Zimbardo writes about hypnosis for pain reduction (page 229) and Michael Murphy writes in his book 'The Future of the Body' about further applications for hypnosis: diseases with a big emotional or psychical elements as herpes or warts (page 332), bodily changes like changing your skin temperature up to alterations of perception.

Hypnotizability
Hypnotizability means the ability to completely surrender the experience. It is a quite stable personality trait.
About 40% of all humans is little hypnotizable, 20% are highly hypnotizable and 10% even very highly. The hypnotic skill is of minor importance for inducting a hypnotic trance. More important is the hypnotizablility of the client. 
Hypnosis and (Lucid) Dreaming
Can you use hypnosis for lucid dreaming? May hypnosis create longer lucid dreams which occur more often?

Joseph H. Dane and Robert van der Castle investigated lucid dreaming frequency of 30 women who had no experience with lucid dreaming. All of them were highly hypnotizable.
All of them got an instruction about lucid dreams but the group who received posthypnotic suggestions to become lucid in a dream could signal a lucid dream with eye cues and report a lucid dream when in the sleep lab more often than the group who did not.
The group who solely had an instruction about lucid dreaming could signal 15 lucid dreams whereas the hypnosis group could signal 33 lucid dreams.
The lucid episodes were even longer in the hypnosis group.

It is also possible to change content of a person's dream via hypnosis. 
Charles Tart lists studies who proved that this is possible, whereas it depends on the single person how much this is possible.
Tart himself also conducted studies to show if hypnosis is suitable to influence the dream content of his experimentees.
Five out of ten subjects dreamt about the desired resp. suggested topic. Although he had only two sessions with each subject this is quite a remarkable result. Maybe he had succeeded with more of his subjects if there had been more trials. 


He also tried to change the way of sleeping of his subjects. He tried suggestions like 'Wake up at the end of a dream!" or "Wake up at the beginning of a dream!", which had good results. 
The suggestion "Do not dream at all!" did not show any result but "Dream all night long" showed an increase of REM time by 21% at one subject out of two.
Maybe his results can be reproduced in future experiments.
But in 1964 Rechtschaffen and Verdone tried to motivate their subjects prolonging their REM phases with money and reported similar success rates.

All of this experiments were performed with highly hypnotic people but only a few trials. Maybe even less hypnotizable subjects will get similarly good results if they  have the possibility to attend more hypnosis sessions.

Using Mind Maps for dream recall

In the book 'Use Your Memory: Understand Your Mind to Improve Your Memory and Mental Power' by Tony Buzan beside interesting hints to improve your overall memory you find the tip for improving your dream recall via Mind Mapping.
Researching the internet and books about dreaming you usually get the advice to write a dream diary, but very few people try using a Mind-Map.

Advantages of using MindMaps

Usually Mind Maps are used for structuring information, maybe to prepare speeches or lectures which works perfectly well. 
In early stages of the preparation or organizing your knowledge you may add some aspects with no problems and without interrupting your flow of ideas.

That is perfect for writing down dreams: Dream Recall often occurs not linearly, maybe you recall the end of a dream first and while writing your MindMap you remember details from earlier moments.
If you start writing your dream diary with continuous text you may get into some complication.

Writing a Mind-Map

I prefer writing a Mind Map by hand using a spiral-bound notepad which I turn horizontal. Immediately after waking up I start making notes.
I begin in the center of the notepad and write down the central topic of the dream. Creative people also may draw a little picture instead of using a 'headline'.

This central point is the origin for branches on which I write down the important key words of the dream. The more details I remember the more branches will be there in this MindMap.
Tony Buzan stresses the importance of finding good key words because this words will give structure to the whole MindMap.
I personally arrange my MindMaps by the different locations of my dreams.

In the following picture you see a scan of a casual MindMap.



The more time I have the more detailed my MindMaps become. At the weekend I write down my MindMap, which lasts about 2 or 3 minutes, turn the page and get an hour of extra sleep, wake up after a dream, write a MindMap and go to sleep again. During my working week I just have time to write the most important things down and make the fair-copy into my dream journal when I return home.

Further Applications

There are several books by Tony Buzan about the application of MindMaps. I have used the MindMaps for preparing speeches. In his book 'Use your head' he tells about students who managed to complete their examination paper in one third of the usual time and even got better marks than expected.
You can also use them as an efficient way for making notes in lectures or meetings.

Online Survey at the Lucidity Institute: Volunteers needed

At the moment there is an online survey at the Lucidity Institute of the Stanford University about sleeping postures, dream recall and dream lucidity.

The survey is running until December 31 2012.
Straight to the questionaire
