Shamanic Drumming is a very specific form of ritual drumming, which when practiced with correct intention, can help to relax us and give some experience of closing down the superficial mind.
The vibration created by the drum changes brainwave patterns from Beta or Alpha to Theta, initialising a deeper state of mind similar to that experienced when going to sleep...
However, theta brainwaves also induce dreamlike states, and some people participate in shamanic drumming in order to have 'out of body' or 'Trance' experiences.
We would prefer you to have a truly awakening 'in body' experience, in which you experience a deeper state of mind and take it with you and integrate into yourself, and your life.
