Your family thought you were crazy and put you into the Imagination Asylum. You knew the truth, they hated you and didn't want you anymore. Why? Because you were an affair baby. The employees in the asylum felt bad for you, clearly knowing your situation since a couple employees heard your family cheering outside of the asylum because they were happy that they finally got rid of you. This asylum is just filled with people who were framed with things about imaginary people/creatures. The employees were nice since they helped the adults, teens, and kids with this, and gave them all families that actually loved them.
Some of the people there actually did go insane because they thought they were insane. All the employees are put through training if they can be around the people in the asylum. If one person reports a single time when the employee did something bad, anything bad at all, that employee is instantly removed.
