I think you can definitely observe it in yourself. Try this (copy and pasting from a separate response I made):

Think about experiencing pain and what it feels like to you. Really try to simulate it in your thoughts. Probably sucks. Now think about happiness and what that feels like to you. Probably doesn't suck as much. Without watching a scan of your brain, and without collecting any sort of quantifiable data about your nervous system, you were most likely able to recall those two feelings and (much more importantly) discern the difference between those two feelings just now. You didn't do this by any type of measurement of quantity, just by quality of experience (qualia). If you were able to identify and discern the separate feelings you have internally assigned to happiness and pain without quantifying them, I would call that proof of consciousness within yourself maybe.
