Ive had a few Lucid dreams, and they were all from DILD's. Though I havnt been able to enter s.p. once and now im just dying to be able to achieve it. I have a few questions about it that maybe will help.

You can enter s.p. at anytime right? I dont have to make sure im in REM to be able to achieve it? (note, i just want s.p. dont mind if i get a lucid out of it or not)

Is it possible to enter s.p. and be able to move? (like a few times ive felt as if i was coverd by a metal blanket, and thought i had made it but when i tried to move my arm it instantly felt normal)

besides those questions any tips on helping me achieve this i would really appreciate even if i end up hating the experiance forever I'm just dying to get to try it once.
