there is no scientific evidence to suggest that people can hear what you say in your head (your internal thoughts) without you vocalizing them out loud. The thoughts and mental processes that occur within your mind are usually not accessible to others unless you communicate them verbally or through other means of external expression.
Your thoughts are generally private and internal, and there is no known mechanism by which they can be directly transmitted or heard by others. People can only understand your thoughts and ideas when you choose to share them verbally, through writing, or non-verbal communication.
It's important to remember that the mind is a complex and fascinating aspect of human cognition, and the scientific understanding of it continues to evolve. If you are experiencing any concerns or difficulties related to your thoughts or mental processes, it may be helpful to discuss them with a mental health professional or a healthcare provider for a proper evaluation and support. They can provide guidance and support based on your specific situation.
