I have one of those floatation tanks in my basement, which I used for a couple of years about 18 years ago, but then never hooked it back up after I moved to where I live now.

My wife calls it my coffin.

I was using it to try to have an out of body experience with, and used to sleep in it at night.

Although I never had an out of body experience while using it that I remember, I did have several times that I felt I must have been trying to leave my body, because my body would jerk like it was pulling me back in.

It was a little boring laying there floating in total darkness just listening to my heart beat, which was usually quite loud from my ears being underneath the water while floating, and my back would usually pop really good after floating in the water for a while.

Maybe if I had known about lucid dreaming at the time it would have been more beneficial to me.

I may set it back up again the next time I move, although it is a little expensive to buy the 800 lbs of epsom salts, and keep the water heated, as I had 4 water bed heaters underneath it that I used to keep the water heated with.
