Have you ever had a dream that you knew was a dream? Were you able to control it? What did you do? In this week's episode of Top Shelf, Katie Drummond dives into the world of lucid dreaming and the technology that's helping people reach the holy grail of dreaming.

This summer, Top Shelf is back and better than ever. We're taking deep looks at the technology we see and don't see, the technology we watch and the technology that watches us. The way we eat and drink, the way we play, the way we work, the way we get around — it's different today than it was yesterday, and it's probably going to change again tomorrow. We'll be here, working through what it all means, and figuring out what's next.

Be sure to check out all the episodes this season, including Top Shelf: I, Spy and last week's Top Shelf: Good Vibrations.
