Are you in the habit of doing more than one reality check at a time? If not, try doing two different RCs every time. Try doing the finger palm one, then the nose plug if the first RC seemed normal. Do this in waking life as well of course, so it'll be second nature in a dream Even being super aware can fail sometimes I think. I've have a lucid where everything felt so super real and right, that even knowing I was in a dream, there seemed to be so much evidence for why that dream was real and not a dream. My first reality check even passsed and I had to do a second one before I actually knew I was dreaming not just thinking I might be.
