Charlotte Church had a "supernatural exerience" when she was 14 years old.
The 39-year-old singer - who shot to fame when she was just 11 years old - recalled "unexplainable things" happening in her hotel room in Switzerland that prompted her to flee the suite after she was left "rattled to [the] core".
She told The Times newspaper: "In Switzerland, at 14, I was performing for a group of dignitaries including Henry Kissinger and John Major in Château de Chillon, a medieval castle on the banks of Lake Geneva.
"After the performance I went back to the hotel. While alone in my room — my parents were in their own room — unexplainable things started happening. The TV started switching on and off. There were noises at the window, like stones being thrown, but I was four or five floors up.
"The whole atmosphere changed and the room felt cold. I legged it to reception and called my parents to come and collect me.
"Later, I realised it was my first experience of something supernatural. Since then, I’ve had a few others that I’ve been more welcoming of — but that one rattled me to my core."
In 2017, Charlotte - who has Ruby, 18, and Dexter, 16, with former partner Gavin Henson, and Frida, four, with husband Jonathan Powell - suffered a miscarriage and despite it leaving her "devastated", she ultimately felt the tragedy of losing her daughter was the "greatest gift".
She said: "For a long time, I travelled mainly out of necessity, always moving, but never really landing anywhere. That changed when I lost my baby daughter in utero, in 2017. She was 17 and a half weeks old when I gave birth to her.
"It devastated me and my husband, but she turned out to be the greatest gift. She taught me how to grieve — properly, not in the way we’re conditioned to in this society, where we bottle things up and soldier on.
"I lost myself in nature at home in Wales, in the forest, in the garden and in my allotment space. I couldn’t stay indoors. I spent every day outside, hands in the earth, walking, weeping, planting, singing. I was for ever changed by her loss and am eternally grateful for that.
"That’s how the Dreaming came to be — the retreat centre I set up in the Elan Valley in Wales. I wasn’t looking for land; it found me. When I first saw it — Celtic rainforest, waterfalls, one of the darkest night skies in the UK — I could feel a new life path opening up before me. It’s a place for healing and for remembering who we are before the chaos of modernity drowns us out."
