Okay i usually listen to "Astral Projection Guided Meditations" on YouTube & they're really good and relaxing. I'd either get to a point where I'm just like "It's not working and just give up and fall asleep"
Or I'd get super numb and have tingles , but never know what to do from there.
Any advice?
You need that numbness in order to no longer feel your physical body.
The tingles are some kind of test in order for you to raise your arm and scratch it. Disrupting your attempt.
If you can get through the tingles and stay numb, and not move while still focusing on clearing your mind and being aware you will eventually success.
When you feel your body is numb, imagine a place, playing a sport or anything. If that does not work, lie there and feel yourself getting more and more relaxed. You might get so relaxed that you slip out of your body or you might instantly ap somewhere. When my body is numb I just step out of myself.
