It’s a recommended experience. Here’s how it went for me:
I arrived at the centre 15 minutes before my session, the place I visited was floatbeyond.com – I sat and had a quick chat with Neil (the owner) about what to expect and I asked about techniques to help me clear my mind. He gave me a magnesium brew and a drink of water then a quick walk around the tank and got me familiar with the buttons and what to expect.
He left the room. I locked the door, put the ear plugs in and then got in to the tank. I pulled down the lid, laid back and allowed all of my muscles to relax. The first thing that I noticed was how strange my posture felt, I am so accustomed to being slouched (driving, sitting at my desk etc), I soon got comfortable. The first 5 minutes had relaxing music, Neil did run through this before-hand (he said the first 5 minutes would have music and then the last 5 minutes would have music to let you know that the session was coming to an end). It was hard to escape my thoughts at first, including the recurring thought of “I am in a tank of water”..... But after 15 or so minutes those thoughts subsided and I managed to start to clear my mind by focusing on my breathing and each time I starting to thinking simply returning back to the breathe.
Around 40 minutes in my stomach grumbled which echoed right through the tank and my senses started to magnify, I felt like my eyes were closed but they were open – I was seeing colours and shapes and had a slight feeling of vertigo (at one point I felt like I was being tipped backwards and at another point I felt like I was spinning slowly anti-clockwise). I could hear my heartbeat and could hear and feel the blood pumping through every part of my body.
It isn’t just about the time in the tank, it’s about the time in reflection afterwards. The drive home was immense, for the first time in my life I didn’t call anybody a d*ck head for cutting me up, I was relaxed. I had quite a bit on my mind later on in the evening and couldn’t sleep at first but when I started to think about my time in the tank it calmed my mind and... I think I fell to sleep soon after.
I’m going to go again. I don’t think it is for everybody. I think you need to embrace the idea of the tank and floating before it will be of any benefit to you.
