Dreams can be familiar and strange, fantastical or boring, but some dreams might be connected to the mental processes that help us learn. No one knows for certain why people dream, but some dreams might be connected to the mental processes that help us learn. In a recent study, scientists found a connection between nap-time(打盹时的) dreams and better memory in people who were learning a new skill.

In the study, 99 college students between the ages of 18 and 30 each spent an hour on a computer, trying to get through a virtual maze (迷宫). The maze was difficult, and the study participants had to start in a different place each time they tried --- making it even more difficult. They were also told to find a particular picture of a tree and remember where it was.

For the first 90 minutes of a five-hour break, half of the participants stayed awake and half were told to take a short nap. Participants who stayed awake were asked to describe their thoughts. Participants who took a nap were asked about their dream after sleep---and they were awakened within a minute of sleep to describe their dreams.

Stickgold, a neuroscientist (神经科学家), wanted to know what people were dreaming about when their eyes weren’t moving, during sleep.

Four of the 50 people who slept said their dreams were connected to the maze. Some dreamed about the music that had been playing when they were working; others said they dreamed about seeing people in the maze. When these four people tried the computer maze again, they were able to find the tree faster than before their naps.

Stickgold suggests the dream itself doesn’t help a person learn --- it’s the other way around. He suspects that the dream was caused by the brain processed associated with learning.

All four of the people who dreamed about the task had done poorly the first time, which makes Stickgold wonder if the dreams show up when a person finds a new task particularly difficult. People who had other dreams, or people who didn’t take a nap, didn’t show the same improvement.
