unbidden
Arriving without invitation
Unbidden means without being asked, invited, or summoned.
Thoughts arrive unbidden when they come without effort or intention: Memories of her childhood rose unbidden.
A guest who appears unbidden wasn't invited.
The word carries a slightly literary or formal tone, suggesting something that emerges spontaneously or intrudes without permission.
