Having an internal dialogue or thoughts that feel like having conversations with "voices" in your head is relatively common and is considered a normal part of human cognition. Many people have an ongoing internal monologue or self-talk, where they have discussions with themselves about various topics, analyze situations, make decisions, or just express thoughts and emotions.
It's important to clarify that in this context, "voices" do not refer to auditory hallucinations but rather to the internal dialogue that everyone experiences. This inner speech is a natural cognitive process that helps with problem-solving, planning, self-reflection, and other mental activities.
The intensity or frequency of this inner dialogue can vary from person to person and can be influenced by factors such as the situation, emotions, or boredom, as you mentioned. During periods of boredom or when there is not much external stimulation, the internal thoughts might become more prominent.
As long as the thoughts or internal dialogue are not causing distress or interfering with your daily functioning, they are generally considered within the range of normal experiences. However, if you find that these thoughts become overwhelming, uncontrollable, or distressing, it might be helpful to discuss your experiences with a mental health professional to ensure there are no underlying issues that need attention.
Overall, having a rich inner world and engaging in self-talk are common aspects of human cognition, and they are usually a part of our everyday mental processes.
