I am not frightened by mirrors. I understand the optical physics of how they work, and I understand perfectly well that when I see my reflection in the mirror, that's roughly what other folk see when they look at me (unlucky them!) I have worked in engineering drawing and CAD, so I'm also pretty good at mentally rotating shapes and perspective.
But I really struggle to use mirrors. I look like I've done battle with a velociraptor after trying to have a wet shave, because watching the reflection of my hand and face just doesn't seem to help me find the spot that I missed. I quite often have to feel around with the other hand to find the whiskers. When I had driving lessons, I was often caught out by my instructor when I had checked the mirrors but not really figured out where the other cars were ("Behind me, right?") Going much further back, I had quite a few accidents involving mirrors as a kid, too, including playing "chicken" with my own reflection (I never hurt myself really badly, but my reflection definitely won!)
I am a little dyspraxic, my proprioception is a bit wonky, and I do have a lot of trouble following when people demonstrate things by showing me ("Why are you showing me with your hands, when I'm going to have to use my hands?") It also brings to mind the idea of "mirror neurons" (thinking about the muscle movements of my reflection as if watching another person.) All of those things seem like they might be factors, but whatever it is, there is definitely something specifically perplexing about mirrors that I just can't seem to get the hang of.
It's not something that's a big deal or ruining my life or anything, in fact, I find the little tricks that mirrors play on me quite amusing very often. I just have a fascination with sensory perception and this particular quirk of my brain, so I'm curious to see what comments anyone might have.
