This is a very common response, and even those know don’t consider themselves claustrophobic may have a fear reaction upon first seeing the tank. After the first float, however, even strong cases of claustrophobia have been dispelled. This may be because you have total control over your environment while floating. You may float with the door open, and you may get out whenever you like. Most everyone ends up shutting the door and staying in until the music comes on, because it’s actually quite nice in there. If you consider yourself claustrophobic and would like to change that, the float tank is the perfect tool.
