I attempted my first WILD to induce lucid dream & during it I felt something like electrical waves flowing through my body & my body feeling like stone.I also felt like my legs were crossed or that I had 4 legs.

My questions are:

1)is this the sleep paralysis?

2)if this is the sleep paralysis , how do I pass it to enter lucid dream , I stayed like this for 20 minutes without entering a dream?

Thank you.
