I guess our brains are responsible for imaging our dreams, so if there is a particular thing that we spend a lot of time thinking about, our brains may be more inclined to generate dreams on that particular thing when we’re asleep.
Hi, good questions. We have dream because our brain is sorting through all our thoughts, ideas and memories whilst we are asleep. Recurring dreams are linked to strong memories and things that we are thinking about a lot. Whats also weird is that we can form a strong memory about a dream, and then dream about that dream memory! Confusing!!
