Why Daydreaming Is So Good for You | TIME

Positive constructive daydreaming (PCD), which is important for healthy mental functioning and cognitive growth, should be encouraged as one of the daydreaming’s many benefits. 

Daydreaming, often seen as an undesirable activity, actually makes up nearly half of our waking hours and may have benefits. Psychologist Jerome Singer identified three types of daydreaming, with “positive constructive daydreaming” (PCD) being beneficial for planning and creativity. The part of our brain associated with daydreaming is the “default mode network” (DMN), responsible for our ability to reflect on our own consciousness and internal narrative. PCD can thicken the cerebral cortex and play a pivotal role in healthy mental functioning, but daydreaming is discouraged in traditional learning environments. Protecting and nurturing daydreaming can lead to more reflective, compassionate, and moral individuals who build a more just society.
