Queen Silvia of Sweden believes the royal palace where she resides is haunted.
“There are small friends... ghosts. They’re all very friendly but you sometimes feel that you’re not completely alone,” Queen Silvia says in a documentary by pSVT.
“It’s really exciting. But you don’t get scared,” she adds.

“There is much energy in this house. It would be strange if it didn’t take the form of guises,” Christina was quoted as saying the documentary.
“There’s stories about ghosts in all old houses. They have been filled with people over the centuries,” she adds. “The energies remain.”
