This week, we talk about what your brain does while you sleep, with our coverage of the science in "Inception!" Oh also, we talk about how excited we are for Toy Story 4 and the new plot for like ten minutes.

Next time, we'll be watching "The Adventures of Buckaroo Bonzai Across the 8th Dimension," and I promise that's a real movie. Hit us with science questions about inter-dimensional travel on our Facebook, Instagram, Twitter, or at [email protected]!
