yesterday night, I was lying down just reading some papers for the exam. After i turned the lights off and decided to sleep, the moment I closed my eyes, RIGHT AWAY, I felt extreme dizziness, feeling of drifting away and huge vibrations. I tried relaxing, surrendering to it. Even imagined that "Rope thing" to go out, but I couldn't. The vibrations were so huge I couldn't fall asleep, yet I couldn't come out of body. It gone to the point of me having to sleep on my stomach, wasting this perfect opportunity. Any advices/opinions on what I should have done in that situation and what should I do in future in situations like this?
