I've been working on using WILD technique for a while off and on, and usually I just fall asleep and fail. But I've noticed someone kind of new crop up, and I'm not sure if it's true sleep paralysis or something else. It happens in the morning after I've woken up, on day when I don't have work and can sleep in a little. I get comfortable again and lie(generally on my back) and try to drift off.

That's when this sort of static-y whishing sound starts in my head(or in at least one case, the static accompanied by a flat tone like a tuning fork that won't wind down or stop), and it sounds like it's coming from all directions sometimes. At the same time, my hands and feet and head go numb. This doesn't even take 60 seconds sometimes. If I don't do anything, it progresses to more of me until I panic and the sound is loud and I only move my torso side to side like a person trapped in a sleeping bag without arm or leg movement. Sometimes I can move my feet and hands again after a minute but the general feeling of numbness remains and everything's useless for another minute. My mouth doesn't work at all and I can't speak at all.

I don't see anything when I open my eyes that's out of the ordinary, and my breathing doesn't bother me or go out of my own control. I can speed it up or slow it down, it doesn't really change anything.

These things can also happen if I'm trying to nap during the day in any position. Also, I've felt like I was moving or sinking into the bed or quicksand or being rolled over even though I wasn't moving.

Some of this screams "sleep paralysis", but should it happen so quickly, and only after waking up and settling back down? What's going on? The partial movement thing makes me think twice about sleep paralysis too. If it is sleep paralysis, where should I go from there?
