I had several Israeli friends in elementary school, though I didn't know what Israel was. I may have picked up some Hebrew from them, as they didn't speak English at first, because when I finally went to Israel at 22 (speaking English and a little Arabic) I would speak Hebrew fluently in these weird bursts.
I am not Jewish in this life, but yes, I had a massive connection to Judaism, though I didn't understand it. Growing up, I thought my mom was "secretly" Jewish, as we don't know much about her mother's side. Ever since I was little I sort of expected this from her, but she always denied it.
