At one point I wasn't seeing anything but I felt my body practically melt into my bed and then felt like I was falling.
This sounds incredibly close to me, much more like a transition actually. During a transition, if you can relax and "let it happen," a dream will normally begin. Keep in mind--you'll get used to the falling and flying and sinking after a while. It's really not a big deal--just a lot of fun--and I wouldn't pay attention to it or be freaked out or anything like that. It's harmless, and ultimately, meaningless. What technique are you using, if you don't mind my asking? When are you trying to do your WILD?

If you feel binaural beats do something for you, no harm in working with them, but I think they are a bunch of bunk. Too many things that work better, in my opinion, to waste any time with them.

If you've been trying for only a few days, and have seen this kind of progress, just keep going. You'll have a WILD soon, or at least you'll wake up in a dream after a "failed" WILD attempt.

And seriously, buy earplugs? You can get fifteen pairs or so for a few dollars at any pharmacy.
