That's not an uncommon question at all. This is a single instance of a set of philosophical questions related to qualia[1], i.e., the question of subjectivity and conscious experience. Richard Dawkins stretches the question a little more by taking into consideration the experiences of other species, such as bats [2] —spatial sense through audition—, and it's not hard to find more[3][4][5] Fun questions to ask (and hard to put into words indeed, I had my share of trouble trying this exact same thing), but I don't think we're anywhere close to answer them. At least not until we really understand what consciousness is.
