Read in a book, an interesting conclusion drawn from the phenomenon of reflection of colours - the colour of any object that we see, is actually the colour reflected by that object, all other colours being absorbed by it - this could mean that what we see is not the 'truh' or 'reality' as we would like to believe. The truth could be the opposite of what we see, or, very different from what we see, or, there could be more than one truth, it could be said - Truth lies in the eyes of the beholder. We assume our existence to be the truth. For all our fretting over ourselves and our lives, our existence could be nothing.
