Sleep paralysis ( don't know how to take over from there)

I have been trying astral projection for past few days. I have reached the sleep paralysed state in the first attempt. I left vibrations through out my body ,I wasn't able to move, at first I thought I was doing it wrong or something and I was scared to go further than that. Next time I tried this same thing happened,I reached sleep paralysed state. Then I imagined there was rope hanging in front of me, I tried to pull at it in my imagination. It didn't work. I understand it's my second attempt so, I'm here to learn techniques to go further after sleep paralysed state.I'm in no rush to experience it. I'm all patient to learn ,and practice.Can someone teach me ? (One more thing I have been doing this binaural ,and subliminal for few weeks. So,I think it might have been a reason for me to reach sleep paralysed state easily)
