Sorry for my broken English, not a native speaker.

I've had 3 OBEs so far and I find it is the best having OBEs/LD through SP because when I'm in SP, it is easier for me to lift my astral body. SP is really a key to my OBE.

The problem is I'm having a hard time inducing SP deliberately recently. I try lying on the bed very still and focusing my mind to become very quiet. I can't get pass the state where my body starts to feel numb and weightless and there's this "Eeeeee" sound (Shellshock effect sound) starts to ring inside my head but that's that. an hour passes and nothing happens, I don't fall asleep, I don't wake up in SP.

Any suggestions? Thank you.
