ONE EYE HIGHER THAN THE OTHER?! Face slanted?!?

So when I look at myself in the mirror head on my face looks great! I tilt side to side looks nice and normal. But when I look at myself in the reflection of the reflection (in the side mirror) my whole face looks tilted! My right eye is an inch above my left eye! My eyebrows too! I was alarmed so I got a ruler and held it up to my eyes to see if they were level and they are! So how come in the side mirror my eyes look so uneven! I also noticed that in some pictures my eyes are asymmetrical, but if I take a picture with the webcam my face looks fine...I'm so confused, which one is the real me?!
