Mirror-touch synesthesia runs in my family. My mother has it much stronger than I do, and will very much feel like she's being touched whenever she sees someone touch another person.
I have an odd quirk on the same thing, but I've learned how to mostly ignore it because it drove me nuts as a kid. However, when hearing someone speak, it feels as if *I* am the one doing the talking, conveyed emotions (obvious or body language) become *my* emotions, and by looking at an object I can feel it's texture on my fingertips. And unlike Mom, I feel like I'm the one doing the touching, rather than being touched. Thus, mostly I'm bloody glad I've learned how to suppress/ignore it. While it can be incredibly neat to feel completely like I'm singing a song without my mouth ever opening, most of the time it's just irritating. I seriously dislike the emotional mirroring because not only does everyone complain to me as I'm instantly completely empathetic to their problems, but I will become angry over silly things simply because someone else is angry. I go about work keeping myself an emotional blank in order to NOT react as my brain wants me to... and then everyone at work thinks I'm angry! Makes me want to throw my hands up in frustration over my broken brain. I would TOTALLY rather experience decades as colors.
