We all have auditory hallucinations during sleep. It's completely normal. Sometimes you can hear them while not asleep. In that case it's called a sympton of schizophrenia. I happen to hear those voices quite alot.

This tells us nothing about the content of the voices however. I've experienced random sentences and stuff and even voices of violent nature. They don't really come when i force them to. But sometimes they take the form of people i know. They will sound just like them and act the same way. Just now i was overthinking the fact that i just ate some meat from the supermarket. I remembered a friend of mine who advised me to eat Halal meat. I wondered if this piece of meat was halal and immediatly got a voice inside of me that said : It's haram to eat this meat .

The interesting part about this was that i had no idea what haram meant. I looked it up on the internet and found out that Haram means ; "Forbidden by the Koran."
I had no idea, i mean i suspected it after the voice said It's haram. But beforehand i never knew this word and nobody ever told me what it meant. I'm pretty sure.
