Reseachers say it's possible to wake up smarter than you were the day before!
In a new study from Israel, researchers played a particular tone when adults were sleeping and followed it with either a pleasant or unpleasant smell.
The same people reacted to the tone when awake by either inhaling or cutting their breath short, as if they expected one of the smells.
They say this proves people can learn new things while they sleep.
