The problem with RC is that they can easily become an to familiar habit. When having short time one can easily do them in a hurry just to do them, almost. I dont think thats what a RC is about. Ive had the same problem and i feel im getting out of that problem now. Your questioning reality, not the RC, the RC is a way to test reality. Along with a RC or before i think you really have to touch the feeling that what you are experiencing right now could be a dream. That everything around you is made up by the mind. This way of thinking drags you along to the present. My favourit RC for the moment is reading text. Whenever im reading text in a dream its always unstable and easy to recognize. If you have experienced a RC inside a dream and seen how in fuction i recommend you stick to that RC, cause then you know what to excpect when doing the RC in waking/dream life. Without i remember it could be a bit confusing to go around and really not knowing what to expect of the RC and how it should work.
