Grandiose delusions

Grandiose delusions are when someone feels very, very important and powerful, but it's not true. They might think they are a famous singer, a king, or a great inventor, even though it's not true. It is like a very strong and unrealistic belief. People with grandiose delusions might also think they are invincible or have special powers that no one has. These beliefs can make it hard for them to function in everyday life because they don't see things the way other people do.
