Hi Selmuir and welcome to Dreamviews.

The importance of RC's cannot be overrated. You need to do a RC every 20 minutes to half an hour untill it becomes a habit so that you will automatically do one during a dream and become conscious of the fact that your are dreaming, become lucid. Why so often? How long does a dream last? You want to be able to do the RC during the dream.

Pick a simple RC that is not obvious to others. The most common suggestion is trying to poke your finger through your hand. That one takes two hands to do and and if your carrying something, difficult to do.
I often do the simple one of trying to poke my tongue through my closed teeth. Simple, unnoticeable and effective.

Best wishes and again, Welcome.
