You are a lost soul still on this earth without a body. You have tried to interact with living humans. You finally figured it out! You' have to use a mirror like a portal to interact and make yourself visible with humans.

The house you have always stayed at had a human who was in high school, around 18 years old. You tried and used your trick, walked through the window, and interacted with his surroundings as he studied.

"Ugh, right when I need to study.. crazy shit happens to me."
