That's the idea at least.

Maybe you were that guy who was there when a portal to the Far Realm was opened and you got a face full of Far Realm energy to the face.

Maybe you were the "lucky" one who survived a failed ceramorphsis and adventurer's kicked in the door in time before the mindflayers could cut out your brain to experiment.

Maybe you got a bit of Aboleth muck on you but not enough to turn you into a slave.

Maybe grandma decided to call up a bunch of tentacle monsters for a gang-bang and forgot to use wards of protection on her womb.
