I am new here, not English so please sorry for my spelling.
I live in Namibia in Windhoek. 20 km outside Windhoek there is a house called the Liebig house (you can Google it or just Google ghost house Windhoek, you might see a picture of the house and read about its history).
One morning my wife and I and our friends decided to go to the house for a trip out of the city, the house is empty for maybe 30 years or more. And we went there for a picnic. I went up the stairs of the house when I heard someone in a whispered voice saying in German " ich kann leute nichtertagen, die endlos reden, it means in English, I can't stand people who never stop talking.
It was a woman's voice and I thought it was my wife behind me, but then I realized that my wife can't speak German and when I looked out of the window of the house I could see her standing outside talking in Afrikaans to our friends a good 30 meters away.
I asked in German that the person who said that should say it again but nothing happened. I also saw a woman staring out of the window and she just disappeared after that, she had an early 1900 dress on. I never believed in ghosts but now I do.
Please Google the house. Hope to hear from you soon.
