for some reason, I just forgot to try the plugged nose one, I always forget to try it, even though it is the one I put the most attention on when I'm awake.
I rarely do the same RC in waking life, but in my dreams either i'm just sure i'm dreaming or i always look to my fingers to be more assured.
I think one should do in waking life the RC that one does more often in dreams - or mixing it with another more reliable RC, and so using the more automatic RC to carry passively the second one.
