[color=red]!!![/color] [I know it’s a long post, but if you want to be sure you’re safe and if you want to know more about this phenomenon read the whole thing. I would have been very thankful myself if someone would have written this to me while I was like you.

I was exactly like you. I also wanted to WILD but was afraid of SP. Even now it sometimes freaks me out, but hey! at least I’ll have an LD after that !
I’ll give you straight and simple answers first. I explain some longer in the spoilers .
SP = Sleep paralysis. You’re paralyzed. I have a special phrase for describing how I feel when I’m in SP:
“I’m traveling with the speed of light in the depths of my brain.” (Invented that one after I had my first SP experience 
).

So, in other words, I describe SP as a “pulling sensation” or “traveling feeling”. It feels like traveling through nothing while you lose control over your body: you can’t move it and you feel extremely tired. (At the bottom I also wrote some methods I use to get rid of SP so you can feel OK with that 
).
It’s paralyze, how can it hurt since you don’t feel yourself anymore ?

I know that one sounded a bit scary. You firstly feel extremely tired and you can’t feel yourself anymore. Eventually your body will start to feel like it’s moving by itself very slowly. However, SP, as scary as it sounds, it is the door to LD. Once you’re in it don’t go back (you easily can do that as I wrote at the bottom), cause you’ll lose your way to the “paradise” of lucid dreaming.
As I said above, I sometimes freak out myself, but that’s nothing to be scared of .

SP occurs in RL each night. It’s only the fact that you’re not aware of it, as your mind falls asleep before SP comes in.

So by doing a WILD you “stress” your mind to remain awake and to leave your body to fall asleep first - that means, it enters SP. But SP is in every dream too, to prevent you from moving IRL if you do in a dream. But if you want to do a WILD you’ll experience SP before entering the dream - and that is as normal as possible (or else that wouldn’t be WILD).
No - and most definitely “NO” !

SP occurs every night. SP is actually nothing more than the body falling asleep. Why don’t you feel it every night ? Cause you get lost in your thoughts and so your mind falls asleep first. So, since it occurs each time you sleep, how can it be dangerous ?!? It’s like saying “Digesting is dangerous !”.
Now, I’ll give you a few highly efficient SP-exit methods. Being easy to remember, you’ll be able to use them to get out of SP in case you freak out too badly. 
1. Deep breathing.
This is the most efficient way to get rid of SP. If you’re in SP and you freak out, the first thing you’ll do is try to move. Seeing that you can’t you’ll freak out even more and you’ll desperately try to move. That will of course get you out of SP, but if you would stay still for only one second and you’d take like 5 or 6 -as deep as you can- breaths you’ll be out of SP in no time.
2. Opening eyes.
While in SP, you’re face is the only one which is not paralyzed. You can open your eyes. If you do that you’ll see your room and the RL. If you look at objects around your room for maximum 5 - 6 seconds SP will slowly go away. The huge problem here is that you feel extremely tired when you’re in SP. That will make your eyes feel so tired that you’ll be too tired to open them. It’s good if you leave them closed cause you’ll have a LD, but if you don’t want one, gather all your strength and open your eyes as wide as possible.
3. Screaming
Sounds pretty embarrassing, but it is very efficient . Again, you’ll feel to tired to do that, but if you don’t want a LD, then gather all your strength and try to scream as loud as possibly. You won’t be able to scream too loud cause SP won’t let you. But it will just disappear.
4. Muscle tensing and breath holding.
This is the hardest as it requires a lot of strength and will. Try to tense your muscles as much as possible and as many muscles as possible while holding your breath. This will slow down the “traveling” speed and you’ll wake up. The major problem is the tiredness: you’ll feel like after you worked a whole day and night and you’ll feel too tired to do that.
But why not combine them all ? For getting rid of SP: Once you feel the pulling sensation and you freak out, just: take a huge deep breath, open your eyes as wide as possible, try to make a sound come out from your lips and tense all your muscles as much as possible. This may sound easy - do it now to see it is - but when in SP everything is like after two days without any sleep.
Now you need to understand that SP is not a gentle thing like a breeze - no, it’s a thunder and a lightning. You’ll know when it happens because it happens suddenly and you’ll feel like traveling through time and space .
TIP: If you want to have an LD using SP try not to concentrate on your surroundings (cause perhaps you’ll freak out more). Instead, try to focus on the “traveling feeling” or “pulling sensation” (or however you want to call it) and most of all focus on your destination. Where do you want to “land” in your LD ?
I strongly wish you good luck and I hope you’ll find out that SP isn’t so bad after you get used to it and you’ll eventually have an LD using it !
". Well, SP only happens sometimes - and, to scare a bit more (just joking), it usually happens when you don’t want it to happen. That’s why I don’t get any SP anymore 
. You’ll come to this stop too, you’ll see 
That’s beside the point. Anyway Its scary but it wont hurt you.
Good for them.
