About six years ago my brother lived in a house in North Miami, Oklahoma. He would sit in his living room and watch TV at night and occasionally feel a presence in the hallway.
His six-month-old daughter slept in the room to the right side of the hallway. Weeks went by and he felt more disturbed by this presence. He would walk into his daughter's room (she would wake up crying in the middle of the night for no reason) and feel unnaturally cold.
So he told my mother, her friend, and I about what was happening. We came over one night when everyone was gone and brought two baby monitors. We put one in my niece's room and one in the living room with us.
After some time the flame of the candle we had lit began to sway. No wind was in the house. We talked to the monitor, hoping to get a response. After some time we heard old-style music and a voice say, "You don't know what hell is like."
It freaked us out and we ran out of the house frantically. We only went back after my uncle (a former priest) blessed the house. We later found out that an elderly man had lived in the house. He had also died in this house.He hung himself in my niece's room.
