"Floatation or Isolation Tank"... good or bad?

[Iam_That_Iam]

"An isolation tank is a lightless, soundproof tank inside which subjects float in salt water at skin temperature. They were first used by John C. Lilly[1][/sup] in 1954 in order to test the effects of sensory deprivation. Such tanks[2][/sup] are now also used for meditation and relaxation and in alternative medicine. Isolation tanks were originally called sensory deprivation tanks. Other synonyms for isolation tank include float tank, floating tank, floater tank, flotation tank, REST tank, flotation baths, John C. Lilly tank and sensory attenuation tank."

I would advise you do a bit of research into John Lilly first.

I used to work in a bookstore that had one available for a fee.

Some people really liked  it,some not so much and a few totally freaked out and needed  help.

The store owner eventually decided it was a liability.

Wow John Lilly combine usage of Ketamine(K) inside the Flotation tank... which apparently lead him to the discovery of certain sentient beings... such as Earth Coincidence Control Office (ECCO) beings and the Solid State Intelligence (SSI) artificial beings...


http://en.wikipedia.org/wiki/John_C._Lilly

SSI --- "..Solid State Intelligence or SSI is a malevolent entity described by John C. Lilly (see The Scientist). According to Lilly, the network of computation-capable solid state systems (electronics) engineered by humans will eventually develop (or has already developed) into an autonomous life-form. Since the optimal survival conditions for this life-form (low-temperature vacuum) are drastically different from those needed by humans (room temperature aerial atmosphere and adequate water supply), Lilly predicted (or "prophesied", based on his ketamine-induced visions) a dramatic conflict between the two forms of intelligence..."

ECCO --- "... Nonetheless, this close brush with the grim reaper's scythe didn't deter Lilly from further solo flights on K; it only reaffirmed his deeply held conviction that his life was being watched over by higher powers of an extraterrestrial origin. Lilly referred to this network of sublime entities as ECCO, an acronym for "Earth Coincidence Control Office." Lilly was positive that all of these fortuitous coincidences in his life (such as Halecki's life-saving phone call) had been arranged by higher forces; and that whatever unfortunate folly fell into his path along the road to knowledge, ECCO would be there to guide him safely through the tunnel to the light..."
