Is this Sleep Paralysis?

So I have been getting this sensations over and over again, without inducing sleep paralysis or whatever this is.

Normally what happens is that I wake up naturally like 4-6 hours after sleeping, so I move on my bed, and I try to sleep again. I am almost getting asleep, when I start to feel like a semi paralysis and all my body vibrating. The first time that it happened to me, I heard like a electric vibration in synchronization with my body vibrating. I always get scared like 4 seconds after I start to feel this, so I try to move my body, and the first time my body moves and the vibrations lower, and I move again, and everything stops.

I have been getting this like once weekly, and I always get scared (don't know why) and get out of it.

One time I got it, and I moved and snapped out of it, then moved and tried to sleep again, and BOOM, again it happens.

Also one time I was dreaming that my mom told me "Maybe you should try to visualize that an exterior force is dragging you to a lucid dream" and then I woke up with the vibrations and semi paralysis, and again snapped out of it by moving.

This has happened like 6 times now...Is it Sleep Paralysis? Why am I able to move but hardly...If I don't move, will it advance and I will get full sleep paralysis with visual hallucinations, etc,etc?

Also today it happened again, and I had a finger in my neck (randomly, maybe I slept like that), but not making pressure or anything, and I got the vibrations and semi paralysis, and I had like a limited vision, like it was hard to see, and I felt like if someone was choking me, but no pain, just like if was grabbing with two fingers my neck (without pain or anything..hard to explain)

Is it normal that I get it without inducing it...many times ??

Just so you know, I haven't had a lucid dream yet

Yes, it definitely sounds like you were experiencing sleep paralysis.
You should consider the WILDing technique to induce some lucid dreams, as it seems you might be able to do it well.

As for it being 'normal', well, many people get sleep paralysis without even trying. It means either you may have an uneven sleep schedule, or you can relax really easily.

Hmm...isn't Sleep Paralysis like you can't move? I mean, it's kinda hard to move but I can..

And anyways, I would try to WILD but...if I say like "tonight, I'm going to let it happen and don't move, and I won't be scared" but when the night comes, and I'm about to sleep I'm like "I won't be able to do it!! Ahhh!"

I always get scared by thinking of SP at night........ (If SP is what I get...tho)

It's a matter of getting used to it. I didn't like the thought of WILDing at first, either. :P

Sleep paralysis doesn't necessarily mean you're totally paralyzed; you can move marginally. Usually when you try to move enough, you snap out of it.
