False awakenings and rc's.

i very rarely to never rc. i should but i dont, unless im lucid when i use them. however i had a lucid dream interupted by maybe 6 false awakenings about 30 secs apart from each other. for some reason in the fa i did a rc every single time and caught it. and thats the thing i NEVER rc, and never when i just wake up, though i should. reminds me of my thought that we know were dreaming on some unconcious level without fully realizing it sometimes. anyway anyone have any ideas as to why this happens?
