You would kill to own one of these if you knew what it was...
A hypnobioscope is a device that enables you to learn while sleeping. Imagine that?! (And we trust you’re thinking about extra learning hours instead of skimping on the day sessions!) Before you get too excited though – it’s a fictional device.
