Out of the ones that you named, I've only ever been successful when shouting "clarity now". But I must say, whenever I've used this one, it's been really effective. Other than that, normally RCs are enough for me to stabilize the dream.

And like MMC418 said, you must believe it's a dream, truly believe it. It sounds silly, but sometimes we might say "this is a dream" without being fully conscious of what that implies. And by that I mean, be fully conscious that your body is fast asleep in bed and this is all a mental build-up, and as such, you have full control of it. If you can stop for a second and realize that, the dream will become more vivid and you'll have more control instantly.
