In Psychonauts, you will have to help the characters overcome their past. For example, the player will have to help the protagonist, Raz, overcome his fear of the circus and the horrors that he experienced there.

This is all done by exploring the characters' mind, reading their thoughts and trying to figure out what their past experiences have been. The game is all about exploring the different sides of the mind and figuring out what's going on in the brain.

In order to help the characters, the player will need to have special abilities, such as the ability to read minds or the ability to touch and interact with objects. These abilities will allow you to explore the mind and the world and figure out what the characters are afraid of.
