In recent years, however, scientists have begun to see the act of daydreaming very differently.

Many scientists argue that daydreaming is a crucial tool for creativity, a thought process that allows the brain to make new associations and connections. Instead of focusing on our immediate surroundings – such as the message of a church sermon – the daydreaming mind is free to engage in abstract thought and imaginative ramblings. As a result, we’re able to imagine things that don’t actually exist, like sticky yellow bookmarks. “If your mind didn’t wander, then you’d be largely shackled to whatever you are doing right now,” says Jonathan Schooler, a psychologist at the University of California, Santa Barbara. “But instead you can engage in mental time travel and other kinds of simulation. During a daydream, your thoughts are really unbounded.”
