Inner dialogue is also referred to as self-talk and inner speech; it is simply having a conversation with your own self. This is done by all people and it is instrumental in reasoning; however, it may become disadvantageous as it may lead to overthinking, anxiety, and depression. Many individuals look down and to their left when they have inner dialogues. These are usually silent or whispered mental conversations while some may talk loudly to themselves.
For instance, someone who is about to have a job interview looks into the mirror and gives himself a pep talk.
