When I feel it fading, it starts to get foggy and stuff, and it's like the sound is getting farther and farther away, but then I say "No. This is my dream, and I am in control of when I wake up. Now is not the time." It generally starts to come back and the dream is a lot longer, and I've also found while doing this, I'm able to wake myself up when I do want to actually get out of the dream. Like not shoot myself to wake up, I just think "Time to wake up." And then I'm awake.
