Question: What is it in our brain that creates imaginary friends? I remeber when I was little i had an imaginary friend and to me he was 'real', I honestly believed I was talking to a real person but it was just someone that no one else could see. So what was it in my brain that made me believe that he was truly there?

ooh, imaginary friends are cool! I never had one, but it is actually very common for children to have an imaginary friend. Some scientists even think that having an imaginary friend is good for your brain and helps you learn other languages and develops your creativity.
The parts of your brain that seem to be involved in this are the medial temporal lobe, which is where language is stored and the prefrontal cortex which is a very important part of the brain involved in personalities and decision making and how we perceive the world.
