Not sure where this was supposed to go.

I've noticed that the feelings I get before falling asleep.

I've had ear-buds in for some nights, listening to binaural beats and I noticed that the sound will change at some points, like the way I'm hearing it, its hard to explain.

I know that the beats will change over time (get lower) but this is different, sorta like I'm losing some degree of hearing before I fall asleep, but I noticed that if I have a thought, any thought it seems, this state of hearing will go away, it generally only lasts a few seconds, because I think of something, I'm not sure what it is, but I feel as if it could somehow help me with LDing.

Then there's my awareness (or consciousness) that slowly fades, like I'll notice that I'm falling asleep and catch myself (I don't know why) this doesn't seem to happen anymore though, I assume its because of the beats. Its like my mind will go blank and...then I'll just sorta notice and be like "oh I'm falling asleep" then it'll go away and happen again, then I'll just stop caring and go to sleep.

So does this happen to anyone else and could these sensations somehow help me with LDing?
