Several Attempts, No Success...

So I've attempted to do several WILDs in the past few weeks.

The first on was the most successful, I became paralyzed, saw the hypogognic (however you spell that) imagery, and then I could begin to see my room through my eyelids. I can't explain what happened next. I just woke up with no real explanation.

I've tried 4 times since then, with no more success then just feeling numb. I just now lied completely motionless for 45 minutes with nothing but a dull heavy feeling.

What am I doing wrong??

I get comfy in my bed, flex and relax, count on the inhale, repeat "i'm dreaming" on the exhale, and remain completely still.

I notice my eyelids twitching, but I'm not controlling that so I don't think that's what's keeping me from attaining paralysis.

You need to be on the verge of falling asleep. How long are you staying up for, if you're doing WBTB?

Did you do an RC after you woke up? I've heard that most WILDs start with a false awakening.
