One time when i was getting ready for school I was getting dressed and i heard a man yell "Hey!" And I looked around seeing no one there i looked out my window I didn't see anyone looked out my door...my dad was sleeping on the couch -3-
Second time was when my brother Jackson was a baby i was in my room watching a movie and well I saw a little girl and a little boy their heads were down so i couldnt see their faces the boy was wearing a white button up shirt and black shorts....his skin was pale but..he was burnt The little girl was wearing a white dress that was ripped her hair was long and black and she was burnt I was shocked and when I blinked they were gone the next morning i was going to the bathroom and in my room was an old woman in a rocking chair and was knitting a blanket
The third time was when I was hearing music in my head a tune that I didn't know
The fourth time was when I heard a woman spoke quietly and said "hello"
