Dejavu happened to everyone and the funniest part it's that you will still be thinking that you are saying the truth but the rest are not getting it right.
This feeling is always fun but to my own research. Its a sign of healthy living but if it happened to someone frequently, then something it's wrong with their mental health.
Yes, this shouldn't happen frequently. At least once in a while as that's okay for a normal human being. Some people will never believe you even if you know it's what is true to you.
Thanks for your comment, Dontee 😊
