re: Anyone here ever done the whole float tank thing?

I thought it was pretty cool.

Water temp and air temp are both 98 degrees so within a few minutes, it's hard to tell what's in the water and what' out and you are floating, so you can also lose situational awareness (which was a little startling at first, like you are falling). Once you get used to the lack of tactile stimulus, you adjust to the lack of visual or auditory stimulus. At that point, you can take a little trip because your brain fills the empty space all the stimuli usually fill. Its hard to describe, but I had random, but vivid visual memories pop up and it was fun, different from tripping, but still fun. My wife had a similar experience.

I'm definitely not some new age weirdo and we did it on a whim. I'm glad I tried it, but once was enough. You definitely need an open mind because the whole setup is weird.
