Has anyone been in a floatation tank? (Otherwise known as Samadhi Tanks, Sensory Deprivation Tanks, Float Tanks, etc.)
Supposedly, the machine helps take away all forms of senses - sight, smell, sound, touch - enough to leave nothing but the mind to do as it will. I've read of some people having strong lucid dreams using one of these tanks. Also, they can be used for deep meditation.
I'm interested in using one, but there are no spas in my area that has one for me to rent some time in. The only other option is buying one, and that is a crazy idea at this point until I've heard that it's a must-have.
Does anyone have anything to say about these tanks?
