There are many mysteries in the world that we don’t know about. Sometimes, we find unique houses on the Internet. These houses look normal from the outside but are amazing inside. Recently, someone found a cave behind his house. He dug for three days and was surprised to see the entrance of the cave.

In the video, there's a big hole under a small mountain. Matt Eary dug for three days and found it. Twin brothers James and Edward, who shared the video on Instagram, were also there. 

They went inside through the small path, feeling like they had entered another world. Along the way, they saw surprising things. At one point, it looked like a big bird or dragon was sitting there.

Inside, there were narrow paths and high hills. They even saw water flowing like a river inside. There was a waterfall inside that had eroded the stones.

The video was shared on Instagram by @actionadventuretwins. They thanked @bccustoms_woodworking_ for showing them the cave. The video got over 3.7 million views and 51 thousand likes. Many people commented on it, amazed by what they saw.

One person asked how someone who finds a cave alone has a whole team of cave divers. Another person thought they saw a sleeping dragon with wings.
