The swan is something unique. It is like an ideomotor response, but clearly not at the same time. It's often more emotive and expressive with its reflex responses. It’s done without trance, but can be used to induce trance.
You can often get it to write, speak or even get up and walk or dance!
It’s direct and easy way to be talking to the subconscious or parts within and get the clear feedback of its response.
The swan is somewhere between a hypnotic process, a suggestibility test, hypnotic phenomenon, ideomotor response and just something else. It is a truly unique way to speak to the parts within the subconscious!

I first learned the Swan from Self Swanning. A youtube clip like this got me started you can too :)
