OK, this only works if you have a DC that you have some control over.
Tell him or her that when you first start to have a dream, that he/she is to convince you that you’re dreaming. NOTE: It is important that you are sure that you are in a dream when you tell him/her this, or else you may be confused on what is “Reality.”
Supposedly, this will give you automatic lucidity!
Hmm… you mean to tell it to come back inanother dream to make you lucid, right? Because if you tell the DC of your current dream that, it means you already know you are dreaming?
I’ve done it one or two times and it worked. One was where I told a DC to remind me I was dreaming when I would lose lucidity - which I did lose at some point in the dream, and the DC did remind me I was dreaming. I was so exited by a DC actually reminding me I was in a dream I woke up shortly afterwards though
