Wow. I have this. I absolutely have this.
Or... at least I had it... but then, "...several attacks happening in a space of days or weeks, followed by months of remission."
In the middle of dreams, or when I'm about to fall asleep, or about to wake up, when I'm in that transitional phase, if I start to become even slightly aware that I'm dreaming, an incredibly loud screech would happen. It would be like a tone, or like some huge metallic scraping, or something like a Nazgûl. It's like the boss fight of tinnitus. Just loud, unforgiving screech. Sometimes I would focus on it, and make it louder, because I knew it was too hard to move my arms to jerk myself awake, so I'd lay there until I was completely awake and it would disappear almost instantly.
Almost every time it happened, it just meant I'd be awake for at least another hour, because I was afraid that going back to sleep would bring it back. But eventually I'd fall asleep without thinking about it and be fine.
