That theory on dreaming's purpose is heralded by Matthew Walker, a professor of neuroscience and psychology at the University of California, Berkeley. "It is thought that REM sleep is involved in re-activating memories and helping cement pathways in the brain between short-term and long-term memory formation," she explains. Kelly Baron, a clinical psychologist and associate professor in the division of public health at the University of Utah, offers a similar sentiment on the purpose of dreams, which mostly occur during rapid eye movement (or REM) sleep. Dreaming would be a part of that process. If that person moved to another area where there are no lions but plenty of domestic cats, their brain would need to forget certain details about lions in order to make room for new ones about other cats. Therefore, that person would need to remember specific characteristics of a lion, like its smell, so that they can avoid the danger of running into one. ![]() A person living around lions would likely categorize cats as dangerous.
