SP really isn't anything to worry about. I can't guarantee that you won't have any frightening episodes, but if you do, maybe you'll be like me and be more fascinated by the experience than anything else. Since you know that what you're experiencing isn't real it can't be that scary. Beyond that, sometimes SP can be annoying because waking up from it can take a great deal of effort. But once you're in SP you can either decide to wake and put in the effort or decide to have an effortless LD and fall back asleep.

Maybe someone who experiences SP when waking up can give you more advice. I only experience it when falling asleep.
