Welcome Lucidit!

Let's be a bit cautious here: Sleep paralysis isn't a step to reach a lucid dream, and it's certainly not something you can "induce" by yourself. It's a sleep anomaly that may happen due several reasons, which don't make it that common among the population.
What may have had happen to you was probably a set of events that might resemble sleep paralysis, but are in fact merely signs that you're body is falling asleep. You may experience twitches, muscular episodes, weird sensations, among many others. When this happens, you should just remain calm and ignore all that is happening with your body, because this events only distract you from your purpose of falling asleep. Remember that excitement is something that can end your WILD attempt pretty fast, so you should focus merely on relaxing and maintaining awareness of your drift into sleep.
