Black magic (Jakarta)

Hey guys. I'm currently doing some research into Indonesian black magic for a book project and I want to ask you to share any stories or experiences you had during your stay here.

As an example, I had a friend who had to hire a Dukun to cleanse his office after people become convinced there was a ghost or spirit lurking around. I also heard a story of a girl using magic to capture the heart of a rich bule.

I'm quite interested in Indonesian love spells, and how they are performed, what are their limitations etc. So, if you have any stories please share and I'll credit you in the finished work. Thanks in advance.
