You didn't minta number?

Once, I'm shitting at my home toilet while playing with my phone when suddenly my eyes fixed at the gap between the door and the floor. Then, I saw a shadow move like someone is standing and moving outside of the door. I'm alone at home that time so curiously I open the door and check around but theres nothing. I'm trying to process what happened logically like maybe some insect fly over the lamp and cause diaturbance on the light but non held the water. I guess it's a mystery that I'll never solve.
