Why do we need to specify a proxy when we inject a scoped bean into another bean?

To some extent I can make out that we need a proxy in case of session, request and global session scoped beans. But why not for a prototype scoped bean? I guess when we inject a prototype scoped bean in a singleton, we need the proxy to get to the original new instance of the prototype bean. Am I right?
