Like /u/Fuyu and /u/newuser, how the human mind works is incredibly fascinating to me. In particular, despite having looked into and practiced hypnosis for about two years now, there's still so much to find and new information to discover on the subject. It's fascinating to me both for how many different ways it can be done, and how it ties into how the human mind functions. (For instance, Transderivational searches are key to some means of inducing a trance state.)
