Vision of The Future in Battle. While in battle, if an enemy is about to defeat one of your party members, a lot of times a vision will occur. Visions temporarily stop the battle and show you the move that the enemy is going to use that defeats your party member. You then are given the option of choosing an ability that can perhaps stop this from happening. Visions last for only a couple of seconds and are particularly handy when battling tough foes.
In the image you can see what a vision in battle looks like. The screen gets blurry around the edges and at the top right corner is shown what move the enemy is going to use that will defeat your party member.
