I’ve been to this pool. At the Biltmore Mansion. Back when I was a teenager my family took a trip there to tour it. I wasn’t too aware of my energetic gifts back when I was younger but I physically felt sick and very uncomfortable in that room. My spouse was with me then, we’ve been together since we were teenagers, and we still talk about how we remember me saying I needed to get out of that room and how weird and creepy the room was. The entire place gave some negative vibes. Now I know why. We also talk about how weird it was to have secret tunnels and rooms throughout the place. They said it was for staff, but it didn’t feel right and we didn’t believe it then either.
