How to know if I have reached the vibrational stage??

Hi there im new to this forum and I wanna know if I'm in the vibrational stage or no. So ok this is what I experience when doing astral projection.... I was trying to project yesterday night in my bedroom I relaxed deep and suddenly I felt vibrations I tried to relax again then it has fade away so I tried to move my astral hand using my mind but my physical hand moves to then vibrations occur after that I tried to relax again it fades away then I tried to focus on my head I tried to move my astral head then I felt like it has splited from my physical head after that I tried to imagine I'm floating but instead the one moving is my physical head then I felt pain at the bottom of my spine after that I fell asleep then woked up in the morning it's like I screwed it up.. So any guides there plz teach me I want to astral project so badly it's not like I'm afraid to astral I'm just calm thank you... Oh yeah I meditate sometimes too and I have my very first lucid dream that lasted seconds.
