What is the place called in inception where you go when you get lost in your dreams?

In "Inception," the place where one goes when lost in their dreams is referred to as "limbo." Limbo is an unconstructed dream space that exists at the deepest level of the subconscious, where dreamers can become trapped and lose their sense of reality. It is a chaotic and empty expanse that is dangerous for those who find themselves there, as they risk getting lost indefinitely.
