How do you Graffiti people?

Good line of thought, I did try the graffiti idea when Daniel first introduced it but it hasn't been something I've tried that much although recently, I've been imagining more outrageous scenarios to help trigger my reality testing in both daytime and night time and I think the graffiti method could easily become part of that...I think.

Here's what I do: Driving is one of my Dream Signs and so rather than just RT every time I get into a car which is so mundane I forget to, I've started to daydream that any steering wheel is in fact a coiled snake that attacks me and tells me to Reality Test there and then. (Snakes feature in my dreams too). So as this is more memorable, I am getting to the stage I can easily imagine this each time in waking life so my RTs are getting better and should bleed into my sleep hopefully with such strong imagery.

As for graffiti, I did wonder about spraying up people's faces that I see in my dreams a lot, some I also see in real life, some not. Either way, I wonder if you can imagine something funny like, a drawn on moustache or glasses on one or all of these family members each time you see them or think of them, that may then trigger the Reality Test reminder in your dreams if you use it as a trigger in daily life?
