I’m in the Isolation tank (Isolation tank)!

That tank in the 1980 movie “Altered states” (Altered states). So, the first revival in 40 years!

Isolation tanks are one-person tanks in which one floats on top of 500 times salty water and relaxes by closing the lid, completely blocking out light and sound from the outside world. Floating in salt water gives you the sensation of drifting off into impermanence, which was all the rage in 1980, but I was in middle school at the time, so I’ve never been in one.

The film was originally conceived in 1954 by John C. Lilly of the U.S. National Institute of Mental Health (NIMH), a tank designed to study sensory deprivation. The experience gradually came to be compared to mystical experiences.

This inspired a film adaptation 25 years later in 1980. It was modeled after Dr. Lilly.
The film is about a genius scientist who, in order to explore the roots of life, takes a hallucinogenic drug obtained in a secret location in Mexico, enters an isolation tank, and becomes an experimental subject himself.

Since man evolved from fish to mammals via amphibians, reptiles and birds, he uses this tank to explore the evolutionary process by traveling back in time to the past, which lies deep within the human brain, but soon unexpected changes begin to appear in his body… The film is a thriller.

So, a middle schooler who loves sci-fi movies finally got his first experience with an isolation tank after 30 years!
I didn’t have any hallucinations, though.
