Dreaming in Spanish, on the other hand, is more of an indication of development than something that can be taught after a few Spanish classes. Sometimes we experience dreams in another language that we are unfamiliar with, but we do not comprehend what is being said. In this case, we should not worry about it and instead focus on developing our ability to dream in Spanish. There are several theories about why we dream in another language. One theory is called the "language in the brain" theory. It states that every language has its own unique structure in the brain, so when we dream in a language that we have never learned, our brains are trying to process these languages in order to understand them. This theory explains why people who are born into families where no one speaks any language other than English at home will sometimes dream in English even though they have never been to England. Another theory is called the "social function of dreams" theory. It states that we use dreams as a way to communicate with others, especially those we love. So if we are dreaming in Spanish, it means that we are trying to communicate with someone else who does not speak English. They are just using the language they know best to communicate with those they love.
