That's an interesting question, niamh! I'd also love to hear how it is for other people! Normally I don't hear anyone speaking in another language in a memory, I just know what they're saying without actually hearing the words. It's hard to explain, but it's like when you're thinking. Or am I the only person in the world who doesn't usually think in words?

I have, however, heard past-life selves or other people in my memories, speak in a language I don't speak, but it's only happened three times. The first two times I heard Jan van Leyden, a person I knew in my Münster Anabaptist life, speak in Dutch, and the other was when I heard a a past-life self of mine almost a century later, who was Dutch, speak. He only said two words, though, namely "Witte Leeuw" ("White Lion"). I posted about it when it happened, no need to repeat it all here

I had no trouble understanding them, but that's probably no wonder, since German is my native language and Dutch and German are very close. I also understand Dutch in this life, but I still need to work a lot at being able to speak it
But these three incidents were the only ones so far. Has it ever happened to you, niamh?
