This was an amazing experience. Everybody should do it at least once!
Sensory deprivation chambers had my interest since the 2003 Daredevil movie with Ben Affleck. Last week, my wife sent me as a father’s day gift, but it was by appointment only, so I was stymied. Today was my appointment. When I got here, I met Dirk, the most mellow dude I think I have ever met. There’s nirvana, then there’s Buddha, then there’s Dirk. In the chamber, you can’t tell if your eyes are open or shut unless you wiggle your eyelids. It’s either the most awake I’ve ever slept, or the most sleep I’ve ever gotten while awake. Left with nothing but your thoughts, your mind wanders in some pretty cool ways. The price is totally affordable, and a far better way to spend money than a restaurant, bar, or theater.
Update: I’ve returned now a total of 5 or 6 times, and have joined the monthly membership. Each time has been really good. There was one time where something was less than ideal in the chamber, and they made up for it very quickly. I continue to recommend this experience to friends and family. If you’re concerned about being left alone with your thoughts, it helps to learn even the slightest bit about mindfulness meditation (even reading the wikipedia entry would probably be sufficient), to make the most of your time in there. Each time, I’m thoroughly relaxed and my mind is calmed. The float chambers are large enough that (at least for 6’3″ me) there is no sense of being confined, because of how completely dark it gets.
