I love this sort of stuff. Most people hate their own recorded voices - I read once it's due to the vibrations that carry through your jaw to your inner ear when you're speaking. Makes your own voice usually sound deeper than it sounds to others. Another neat effect along these lines is that since you see yourself mostly in mirrors, which are reversed images, most people prefer the appearance of their mirror image to their actual image. It's one of the reasons why a lot of people don't like how they look in photographs.
Also, the spotlight effect studied by social psychologists says that on average, people think others are paying much more attention to them and notice a lot more about them than they actually do. People also consistently overestimate how good they are relative to others in common skill areas (social skills, writing, attractiveness, etc) and underestimate how relatively good they are at uncommon skills (computer programming, marathon running, etc). It's not unusual to see 95% of people tested rate themselves as above average in the common skill areas, and the exact opposite in the uncommon areas.
