Philosopher Daniel Dennett calls seeing yourself in this way heterophenomenology. Basically, he suggests when you explain why you feel the way you do, or why you behaved as you did, to take it with a grain of salt, as if you were listening to someone tell you about their night out. When you listen to someone else tell a story, you expect some embellishment and you know they are only telling you how the events seemed to transpire to them. In the same way, you know how reality seems to be unfolding, how it seems to have unfolded in the past, but you should take your own perception with a grain of salt.
