Well, here's a story. It's not that scary, just weird I think. This story is about my mom's late sister. It happened sometime in the early 70s when my mom was in Form 3.
Her eldest sister was 9 months pregnant at that time. One night, she dreamed about a white crocodile at the other side of the river asking for permission to adopt her yet to be born baby. She agreed (just a dream mah..). When she woke up in the morning, her stomach was flat and the baby was gone just like that. She cried like there's no tomorrow. Nobody could believe it. It took her months to recover.
A few years after that she dreamed of the white croc again. This time there's a little boy playing beside him. As the years passed by, sometimes the boy would appear in her dream, growing up healthily.
My family believe the white croc was actually 'orang bunian'. They are humans, like us. But we can't see them. If the boy is still alive today, he would be in his 40s.
Sadly, she passed away in the late 70s, before I was born.
