A childhood belief about imaginary friends

I used to have a family made up of a lady, a robot and a few other characters i can't remember, all in my mind. They would never appear before me, but they'll just advise me in my mind. Sometimes, the robot would talk so loud, I had to shut my ears, but to no avail. But, they have disappeared for very long already. I guess it was my mind's way of bringing me on the right track and making good decisions as a small kid.
