Okay kiddo, there is a kind of story that some people in India believe in where certain special cobras, called ichchadhari naag and naagin, can turn into human-like creatures.
These cobras are said to have special powers and abilities, and some people even think they can live for hundreds of years. When they turn into human-like forms, they can do things that people can do, like talk and walk around on two legs.
Sometimes, these ichchadhari naags and naagins use their powers to help people, but other times they use them for mischief or revenge. There are even some stories where they fall in love with humans and try to become humans themselves.
Now, we don't know for sure if these stories are true, because we don't have any scientific evidence to prove them. But some people really enjoy these stories and think they are a fun part of their culture and mythology.
