The hardest thing to convey to you in imagery is the feeling of the warmth of the pool and how special of an environment it creates. The water is heated to a brisk 96 degrees, and often reminds people of being in the bathtub. The warmth is there to evoke a sense of comfort, facilitate muscle relaxation, calm the nervous system, decrease the pain response, and increase blood circulation. That temperature is also the same as amniotic fluid, so there is thought that people have a sense-memory from the womb for this environment. Also, if the temperature of the water is the same as skin temperature, then the recipient can begin to lose track of their body in space. This feeling, coupled with the movement in the pool, can help to give people a feeling of flying in endless space.
