Recently got inspired by adventure time

So I was watching this breakdown of an adventure time episode and it had Finn the human go into this cave were he closed his eyes and walked through a door but when he opened his eyes he was transported back into the cave I want to I corporate this idea into a dnd homebrew campaign but I feel like the end result will take a long time to finish because in the episode of adventure time Finn has to find the exit door and go back through the door with his eyes open any ideas on how to speed up this process of finding the door
