To OP:
Yeah, I've had that many many times, most nights in fact. I'll be dreaming and it will get really vivid, then I'll realise I'm dreaming and the dream becomes less real, and very fake. I can control the entire dream at this point with my thoughts or imagination, but the whole thing is created in my mind and feels completely made up. It's at this point that I just let go and wake up.
If it's a lucid dream I'd love to be able to enter it consciously when it's still real and not have the whole fake feeling take over.
If it's a precursor to astral projection that would be even better, but I've never experience the ringing sound.
Either way, I'm going to keep practicing and see what happens, that's the only thing I can suggest.
