The following excerpts are from a recent BBC News article on floating:
"The [floating] sensation is one of no sensation - your mind becomes untethered from your body. There's nowhere like it on the planet."
Gary Mossman is a 26-year-old tattoo artist in Basingstoke.
He has started to use flotation tanks to explore what he refers to as the "theta-state", a drowsy or trance-like state which he hopes will help him be more creative with his tattoo designs.
"It's about making a blank canvas in your mind so you can then picture something completely original. It's a little like the stage just before falling asleep, where you have a really vivid imagination and things just appear in your head."
Floating is even making its way into the arena of elite athletes.
"I do it to help visualize ahead of my next competition," says Adam Adshead, a jiu jitsu martial artist from Manchester. He has "floated" every week for the past 18 months.
"Having no distractions at all makes it much easier to focus. There are lots of sports psychologists coming round to the idea of using float tanks as a way to help sportspeople visualize performances."
