Am I close to astral projecting?

So recently ive gotten into astral projection and chakras and stuff because my friends are into it and I am a lucid dreamer. So I try to do this by lying in my bed and breathing into my stomach, which im able to do easily because i play trumpet and swim. I try to focus on the rope visualization and not move at all, and I get to a point where my body is vibrating. One of these times, my arms were vibrating so much that it felt like my hands were completely distorted and cramping, and there have been times that my eyes flutter like in rem sleep and ive seen shapes (nothing recognizable/just shadow like objects) with my eyes closed and light changes thru my eyelids. I have not seen any part of my soul exit my physical body, and I seem to always be conscious of my physical body. How close am I/what do I need to do to complete the quest?
