A vetala is a spooky creature from Indian mythology, kind of like a ghost. Think of it like Casper the Friendly Ghost but not so friendly. Vetala is said to be a spirit that possesses dead bodies and can move them around. It's like if someone else got into your body and controlled it for a while.
The legend says that people should be careful around vetala because they can be mischievous or even dangerous. They might make strange noises, move objects around, or try to scare people. If someone encounters a vetala, they should be brave, and not fall for its tricks.
Vetalas first appeared in ancient Indian mythology, and they often show up in poems, plays, and stories. Some people still talk about them today, especially during spooky times like Halloween. But don't worry, they're just pretend creatures, and you're safe from them.
