So close to ap

I believe I was on the verge of my first astral projection, but I couldn’t quite roll out of my body. I could feel my body starting to separate, and it was making me tense up/sweat. I was rolling in my head, but it didn’t take me out of my body. After a while of this, I tried the float method, and couldn’t get that to work either. I went for a Hail Mary, and tried to sit up as fast as I could to throw myself out of my body, but I ended up waking up instead. It seemed like a 50% chance it would work so I had to try it. And now I’m on Reddit sharing my story and asking for advice.

How do I successfully separate?
