NatGeo: Do spiders dream?

Spiders might be a nightmare for arachnophobes, but do they have them?

A new study by the University of Konstanz suggests as much. Researchers found that jumping spiders experience a sleep-like state with rapid eye movements similar to those observed when we dream.

Rapid-eye-movement sleep has been observed in other animals, particularly mammals but also fish, birds and reptiles.
