Does our brain predicts future!

Does our brain predicts future or it just play games with us and fools us when we are asleep.
Remember whenever we are asleep, dreaming and waiting for a moment to come, it keeps on delaying further and further, and just when its going to happen some external factor wake us up.
For example there is this explosion which is about to happen in your dream and it waits for the exact moment when someone knocks the door or for a vase to fall.
Same is the case when something terrible is about to happen.
As if brain knows what is about to happen next moment in real world. And we all are familiar with, how convincingly brain incorporates real world's sound and environments in our dreams.
That's how our brain cheats with us and deceives us. Or does it really reach to a level where it's easy for it to predict near future!
