Some say the doll can be heard talking when it's left alone in a room and is found with its head turned in a different direction. It is said that it spoke in a Malay language and sound like an adult female.
Original owner found that the only way to get rid of it and make sure it won't come back is to cover it's eyesight. The curse is rumored to have passed on to someone else who found it and untied the cloth unknowingly
Edit: turns out it the Arabic thing meant "bismillah". I think it's to trap whatever jinn or curse is inside from coming out or following the owner back home. Others speculate it's a product of black magic.
The doll has been missing since.
On the very day the locals started trending a freaky suicide (guy hanging beside an apartment block) and murder case which is highly unusual in Singapore but is most probably a coincidence and not related.
It's irrelevant but you don't see multiple creepy images start appearing on the same day in a small country like singapore so many assumed they were all linked though obviously it's not.
