some real coast to coast with george noory here

I sense a lack of one, big, crucial element here: breathing. 

Controlled breathing is a fundamental item for this kind of things, as it slows down heart rate,, regulates oxygen levels in your blood and relaxes your body, not in the "ooooh, i'm so relaxed right now" way, in the "I'm letting my body go for a while" way. 

Learning to breathe the right way educates your body to recognize wether you (and by "you" i'm talking about your inner consciousness, the one that inhabits your physical body) are just doing your daily stuff or sleeping, or meditating. Try this for a 20-30 days period, straight: when you go to sleep, lay on your back, your hands by your sides or on your legs. 

Close your eyes, and focus on the glittering black curtain behind your eyelids, knowing it is a thin layer of skin just a few centimeters away from your retina: concentrate and perceive this physical distance. In the meanwhile, empty your head from ANY (repeat: ANY) thoughts, wether they're verbal ones (your own voice commenting your actions or what's happening to/around you) or just feelings/sensations. 

Once you're set like that, start a breathing cycle, this way: 6 seconds in-breathing, 3 seconds hold, 6 seconds exhale, 3 to 5 seconds hold (empty lungs). Try to make this as natural as possible, not forcing nor contracting any muscle, thus using your diafram and latting the air reach the bottom of your chest - feel your belly as it inflates, don't breathe with your upper chest. Imagine your lungs as a tank, being filled with a liquid: it starts from the bottom and then comes up as it fills up. 

Don't count rationally - keep this process as instinctive as possible, and give yourself and your body time to learn this. We all breathe the wrong way, filling and emptying our upper chest too quickly. That should help setting up a friendly environment for every kind of meditations and OOBEs.
