Hmm... I had an experience very similar to yours actually. I'm also starting out, but unlike you I actually have no natural talent for lucid whatsoever. In any case, I did manage to get pretty far in a WILD recently.

After relaxing, losing concious thought of my body, my mind was becoming fuzzy. I started to concentrate on '1, I am dreaming' etc, when I noticed the only thing in my head was a hum of some sort. I decided to start concentrating on that, and immediately it started to become louder. And louder, and louder until is was ringing violently inside my head. I'm not so sure how this relates to hypnogogic sounds, but I know that this only happens during my WILDs. At the same time, I began to feel some strong sosematic sensations, I felt as though the rooms was spinning and I wasn't in my body. I then realised I was beginning a WILD and got excited, which returned me to consciousness.

Finally, welcome, good to see someone from a place outside of Europe or North America! We do have quite a diverse bunch here... and I like you sig, by the way.
