RC's and Relibity

i have been wondering about RC’s recently if they are reliable.
this started after two dreams where a RC told me i was awake and i just went back to dreaming, woke up latter and realized it was a dream.
i don’t know if anyone else has said this before but, my theory if you want to call it that you do an RC IRL and of course it shows you are awake. now for the first few RC’s in dreams the RC does something wrong and you know your are dreaming. now eventually i think your subconscious will learn that the RC should tell you are away so it will start to make you think you are awake in the dream. thus making the RC useless until you do an new one i guess.
what do you people think?

The most reliable reality check for me is the memory one. Try and remember what you’ve done for the past hour and how you got to where you are. If there are gaps then you are dreaming.
