Almost Astral Projected

This afternoon, after an hour or so of trying to take a nap, I finally (and I say 'finally' because it is usually very hard) became conscious at the point where I was entering sleep paralysis (I felt the vibrations of my body wanting to fall asleep and then seized the moment consciously!). I applied the rope technique, where basically you imagine a rope coming out from you and extending up into infinity, and you imagine yourself climbing the rope to 'pull yourself out' of your body. I saw my astral arm and my astral leg coming out, but my head was still in its 'body position' and so hard to pull out. What is usually annoying is the acute noise that I hear as I shift into another plane, that gets louder and louder. I know it is the same noise of my tinnitus condition that I have all the time, but it only gets very loud when these shiftings are taking place. I think the reason people have tinnitus is because there is a slight interference with another plane for some unknown reason, or that they are catching signals from that other plane (I wish I knew how to get rid of that noise for good!). Unfortunately, I became a bit scared because these moments happen rarely and because being consciously paralyzed is not very pleasant when you are a beginner. I hope I will be more successful for times to come. I do feel that the vibrations to sleep paralysis are more easily 'detected' when trying to take a nap in the afternoon or early in the morning, when you wake up for a moment and then try to finish your sleep.
