Why Do We Dream?Įveryone dreams, including babies and animals (if your dog howls in his sleep, he’s probably dreaming of confronting other members of his species). And if you have ever experienced Deja Vu – the feeling of familiarity with something that’s not supposed to be familiar – it may have something to do with your dreams.
