I needed to join this forum to share my experience. I Googled what does it mean to hear a Flute in a full moon night, 13.09.2019 (Europe).
I woke up around 4am, like usual, and I heard a Flute playing in the distance. There is a small wood in front of my house, it came from that direction. I live in a village. There was no Wind (a mild late summer night) and no one in the neighborhood plays instruments. Never heard it before or since than. I am a skeptic and I believe only what I see. Yes, i went out on my balcony and saw nothing, just heard this melody that got more and more far away from me. It was an irregular random melody, as if someone practiced. The memory of this night is still following me and I would like to share this, maybe someone else heard it somewhere...
