The question of whether visually impaired people dream is an interesting and somewhat complex one. It can be answered with a yes, but to varying degrees.

"Patients that have acquired blindness after being able to see as the result of an injury to the eye or the optic nerve may certainly have visual dreams," says Mark Stecker, chair of the department of neuroscience at Winthrop University Hospital, in Mineola, N.Y. And those who have mild visual impairment "will have normal visual dreams."

But what about people who were born blind? Do they dream? And if so, do their dreams contain vivid visual imagery? Take a look at the video above to get the full answer from USA TODAY science reporter, Elizabeth Wiese.
