I want to preface this that I am not "woo" at all but do find this quite weird! I have a non identical twin. I went to a new gym a few months ago in a different city and told the class instructor my name. He called me by my twins name the full class (there's zero chance he'd ever met my twin). I told him at the end his mistake and he'd actually been calling me by my twins name. I met my twins friend for the first time this weekend and she had introduced her new boyfriend to my twin. Her new bf later said to her that my twin seemed really nice but he kept wanting to call her by my name (he had no idea about my sister being a twin or what my name was and definitely never met him). Maybe not woo at all but I'm a bit spooked by it?! Or just a weird coincidence?
On a different note, when we were younger we definitely used to have a weird telepathic thing going on. My twin was away on an overnight as a child and ended up in hospital badly injured.
Before my mum even knew about it, I was inconsolable for no reason and curled up in pain,, if then made sense after the phone call.
Just a weird twin musing that my rational brain is struggling to comprehend!
