Daydreaming is good for our brains

When we daydream, we form alternate-reality thoughts with the assistance of the default mode network - a cluster of brain regions. Researchers found this network is most active when we are not focusing on anything.

• Neuroscientists think this type of creative thinking can help our brains reflect on the past and plan for the future.
• Other researchers surmise it might reduce anxiety, boost creativity and improve memory.
