ive been doing Rc's randomly throughout the day even if i do not notice anything strange... should i Rc only when something abnormal occurs or i notice a dream sign?

also my Rc is Simply Oberserving the room around me.... asking myself if i am dreaming then looking at nearby text or clocks... and i thought this was okay but..

i was talkin to my brother and he said that he just looks at his palms and ask "im i dreaming" and said i should do the same..but i really dont want to change my Rc now...

so the other question i have is is my RC okay because now i am questioning my Rc method..... and dont know if it is acceptable or not
