Yea I'm pretty sure the intention is to just make it a habit of "Oh, I haven't reality checked in 4 minutes!!!"

The thing about the twisty is that, you may look down, not see it, and go "oh I forgot it" or "oh it fell off". Make sure you combine it with a reality check that serves as a marker of the dream world. IE something impossible that signifies that you are in fact dreaming (multiple fingers, objects can be phased through, you can breathe when you shouldn't be able to, you can fly, etc.)
