I Think I'm Close

I've been interested in astral projecting for about 11 or 12 years, and as I get older, the more it makes sense to me. When I started learning about it and actively trying to project when I was 10 or 11, I would do everything wrong because I never really understood what I was doing. Luckily, now that I'm turning 22 soon, these astral projection techniques and concepts are starting to click for me. I'm not exactly the most consistent at practicing but some tips and pointers would help me out a lot, especially because I think I'm getting closer to actually projecting.

So I don't really go by any specific techniques right now, I kind of just lay there and relax while trying to not fall asleep. I close my eyes, and stare into the void while letting my thoughts wonder, gently bringing myself back every now and then when I feel like I'm drifting off to sleep. I just watch the shapes and lights behind my eyelids, or focus on the ringing in my ears that we block out most of the time, and ignore my body when it's telling me to move (most of the time I'll listen to music or guided meditations). After maybe 20 to 30 minutes, I get to points where I either can't really feel my body anymore, like I'm physically numb, or it feels like my limbs are spinning and floating off like food coloring in water or smoke in the air, so much so that sometimes I feel like I'm just a disembodied head. Sometimes I feel a slight buzzing in my body but nothing intense. That's as far a I get though before I say forget it and move to a more comfortable position to go to sleep because I can't seem to get passed it. I've read that those are signs that I'm getting closer and I just need to lift up and out of my body at that point, but for some reason, I still feel like it's not enough. I still feel like if I do anything else I'll ruin the process and I'll have to start over. It's frustrating to say the least especially because I do feel like I am so close, it's just out of reach.

I'm pretty sure I have projected once on accident when I fell asleep listening to music. My eyes were open and I was super close to the ceiling, and then it's like I snapped back into my body and opened my eyes (even though I thought they were already open) and realized I just woke up. So I know I can do it, and I'm not scared of much so it's not doubt or fear holding me back. I'm stuck and would really appreciate anything anyone can tell me that would help me finally reach the last stage and actually separate.

Thanks.
