I'm not sure about what others experience. It's different for everyone. I can only speak from personal experience. The worst thing that happened to me during SP was monsters coming to get me. A couple of times I saw some things at the foot of my bed. Honestly though after I read about it and found out it's natural it's been a cool experience ever since. I never imagine those things anymore. Now it's just a feeling of tinglyness and joy because I know I fixin to have a lucid dream.Don't worry about all the scary stuff. You know that there is really nothing to be afraid of. You know that it's a natural thing your body does to keep you from harming yourself in dreams. If you know that then your mind will have a tough time playing those kind of tricks on you. Just remember that when you start to get that sensation again.
