This article covers exactly what it says, what babies (neonates) dream about. Neuroscientist believes that the R.E.M sleep that neonates have isn't like the rapid eye movement sleep adults have. With there limited pool of experiences, neuroscientists believe that babies dreams don't start taking the shape of ours for the first few years of life. Instead they believe the R.E.M sleep is for creating those pathways between different neuronal pathways, and in later years help with developing speech. Even when we are 4 and 5, most children were found to have plain dreams, were nothing moves or acts upon anything. Children don't start having the vivid dreams till about 7-8, which is about the same time that the child starts developing self identity.
