Every Night, My Mother-In-Law Knocked on Our Bedroom Door at 3 A.M. — What We Discovered Changed Everything

That night, the knocks came again.

I kept my eyes closed, pretending to sleep while my heart hammered.

The next morning, I reviewed the footage.

What I saw froze me.

Margaret stepped out in a long white nightgown. She walked slowly down the hallway, paused outside our door, glanced around, and tapped three times. Then she simply stood there, motionless for ten minutes. Her face was blank, eyes hollow, as if listening for someone… or something. Then she turned and walked away.
