Exploring the possibility of decoding our dreams

Typically, we  spend more than two hours each night dreaming. But often we wake with only a scant recollection of our dreams, unable to piece together the seemingly random events.

This recent ASAP Science video explores the latest research on visualizing and recording dreams. It's fascinating stuff.
