If you've read THE BLACK LADY posted by the gal, mine would be a similar case.

This happened some time ago in my flat. I was deep in sleep on my bed...when suddenly i was awaken by some voices... I slowly opened my eyes, & as it was dark, i couldn't really see well. But I could tell what it was, or rather what they were. Standing right beside my bed were two figures...a man & a woman. They were speaking in some foreign language which sounded very much like chanting. To be precise, they were not really speaking, I'd call that scolding. The tone was very harsh, & they seemed very angry with me.

This happened only once...& I wonder when they'll be back. This time, I'm well prepared.
