The whole conversation about dreaming somehow is focused on humans and spirituality. Anyone who ever had a pet at home knows that cats, dogs, even birds clearly experience unusual brain activity when asleep: manifestations in the form of shrieking, panting, sometimes screaming and waking up confused or scared obviously point to something that is suspiciously similar to dreaming.

This brings us to question: are animals spiritual? See, it can get complicated real quick... But nothing beats a good night's sleep, regardless of beliefs.
