Sometimes I see things, but they've never frightened me. Even if they were intense, knowing that this was part of something that I was inducing would be enough to calm me..

HyperNova, your attitude about SP is probably the reason why you have not been able to turn it into a lucid dream. SP is a great state to drift off into a dream....If you are already set on being frightened by it, than you most likely will. Try to clear all of those preconcieved notions about SP and then try to drift into a dream while you are in that state. You might be kind of suprised by what you experience.
