And if you're lying on your side, one eye open, left and right are still reversed... nothing to do with binocular vision or with orientation then - the 'simple' answer is that a mirror image is simply that: clockwise becomes anti-clockwise, left becomes right, helices spiral the other way... a mirror in a forest with nobody looking produces the same effect. You could draw little diagrams with light rays etc. to illustrate but it's a tad difficult in text... try visualising the reflection as a 'virtual' object existing behind the mirror and all should (or might) become clear.
