wakeup technique affirm "wake up!"

[weagle]

has anyone tried this affirmation I read it from this website http://mymysteries.net lesson#1 on mystic awareness or conscious awareness raising?  Like you affirm it with feeling and of joy for a few weeks the word "wake up!" to yourself in a mirror and to the family or to the world you view etc..  I think this can trickle down to the subconscious and then start triggering things like being aware you are dreaming or maybe even be intuitive on situations etc..  I know this kind of thing does work because one time I did body awareness exercises fell asleep and realized in one dream sequence I said to myself hey this is not real I'm in my body in my bedroom doing my body awareness exercises and became lucid and aware of it but its freaky to use this "wake up!" affirmation because it can lead to many possibilities besides lucid dreaming to obe.  any comments on this?
