Hall of Infinite Doors

As you enter the cave, you find that it is pretty much impossible to see. You even wait a few minutes to get your eyes adjusted to the dark, but nothing really changes. Getting colder and more tired, you end up pressing your hand against the cave wall and blindly start to walk deeper into the cave.

After a few minutes you stop and freeze up as you hear a growling in the distance. It could be a bear, wolf, or some other angry beast. You're really not used to this new time period yet and you don't even know if it is Earth. You realize that you could be in another dimension, where any kind of mythical beast or monster could exist.

Now realizing all this, is it worth staying in the cave?
