Do animals dream when they hibernate?

When we dream, sleep becomes storytime. You might see an old friend, go on an adventure or show up to a test without having studied. So when animals hibernate for a long stretch in the winter, do they have epic, long dream stories too? We asked dream researcher Tore Nielsen to help us find the answer. Got a question that’s keeping you up at night? Send it to us at BrainsOn.org/contact, and we won’t hit snooze on finding an answer. See omnystudio.com/listener for privacy information.
