Ready to have your mind blown? Join Eelis Rankka, Tommi Salminen, and Jukka Pelttari on their fishing trip under Lake Saarjarvi in Vaala, Finland through this video. The adventure starts out pretty normally, with the fishermen walking along an ice floor. But soon, things start getting a bit surreal, and the viewer's perception is forced to shift. Nothing makes sense until the end, when you realize that everything is an illusion. The effects are stunning and trippy all at the same time.
