I will tell myself jokes and laugh at myself, often! Is this a disease? It is no problem to communicate with classmates. Very talkative. It happens when you are bored! three

Of course not. A lot of people do. They laugh when they think of funny things in the past, and others will feel puzzled. But as long as they are happy, it only shows that they know how to entertain themselves. This is good, they can make themselves happy. It also shows that they have many beautiful things in their hearts. I hope you can be happy.
