 Americans are spending an average of two and a half hours a day or 873 hours a year dream scrolling on the phone or computer. Half the 2,000 respondents to the study said they dream scroll while at work. Gen Zers spent the most time dream scrolling, a little more than three hours a day. Boomers spend the least at about an hour. The majority of those who responded, about 71%, however, said dream scrolling is time well spent.
