Radiolab - Wake up and dream

How do you confront the recurring nightmare in your dreams?

If you have a nightmare with a scary figure that haunts your dreams every night, how do you get rid of it? The answer is like something out of Vanilla Sky or Inception, and it can be harnessed to turn your dreams into the Matrix.
@alexcartaz I loved this story. Re-told it when having guests over this last weekend, and it prompted everyone to talk about the wild and crazy dreams we've all had. Really fun.
