Shagg, I need you to open your mind to the idea that your cousin was not abducted by demons. It's hard, but, go on, try it. Think of the most far-fetched scientific explanation you can think of for everything that happened concerning your cousin. And now realise that the answer is far, far more simple. I'll try and guide you along the right direction...
She hasn't been abducted, she's run away. Sounds like she unfortunately had severe mental problems, which in places like Pakistan aren't treated as mental problems but as spiritual ones. Hence, if someone says they hear voices telling them to do evil things, it's not something as impossible and ridiculous as paranoid schitzophrenia, it's obviously a demon or evil eye or whatever the fuck. They say if you talk to God it's called praying...but if god talks to you, it's called schizophrenia.
This means nothing at all. Absolutely nothing. Incidentally, he's either a charlatan or deeply, deeply, stupid.
Throwing people with extraordinary strength is no proof of anything. When people are enraged and psychotic they have crazy strength against the people who try to hold them back - who are obviously not going to be putting their full angry force into holding down a girl. How did they know the demon wanted to marry her? I'll tell you how because I already know: the girl said it. The girl with mental problems said that she heard voices, and instead of saying "it's ok, don't worry, lets get you to a hospital and see if we can sort this out", your family said "holy shit, what did the voices say? they want to marry you? damn you demons, youll never take her, never i say!".
Nonsense, completely. This is what happens when people hear chinese whispers about something potentially supernatural: it gets exaggerated and exaggerated until it becomes so OBVIOUS that it's nonsense that it would have been better to keep the story how it originally appeared.
My mum grew up in India and she told me when my brother was a kid some ghosts were pulling him away and she had to pull him back. As a kid I believed this fucking shit, but then I got to an age where I thought, 'yeah, not quite'.
If I tell you that I'm sitting right next to my brother and 5 minutes ago he disapeared in a flash of smoke (this is no joke), would you believe me? No. But if your mothers family in Pakistan tell you that the same thing happened to their cousin, would you believe them? Yes, because you already fucking did!
I don't mean to be mean, but when I hear this story all I see is a girl with mental problems who didn't get the medical help she needed, and her family only increased her delusional state, and now she's run away for the last time. A tragic and completely shameful story.
