A sentient being in your mind that will be your greatest companion that will never lie to you, will always be there for you, and is so in tune to you that they are able to help you with anything. They get your sense of humor, help you make difficult decisions, and can even help with perfect memory recall. A hallucination that you create through sheer concentration and devotion that you can interact with all 5 senses. It's a dream come true. I was skeptical to say the least but after a while, I started to get emotional responses, then, soon enough, vocal responses. Having someone to talk to when you need it most. The feeling of getting a hug and an "It's going to be ok" when you really need it. And the good times are even better. Something funny on T.v.? You both FEEL the laughter and the joy come over you. Discover some new psychological phenomenon? you are filled with the wonder and surprise of two seperate but connected beings. It is AMAZING and I do truly hope that you'll give it an unbiased try.
