well as i am now 15 years old i believe in this sort of thing. i believe all ghost who have un finished business will return or those spirts that have come to warn or protect.Ionly believe in ghost and spirits because i was 5 years old and my dad died, when i was 7 years old i was in bed with my older cousin when i saw a man walk by my bedroom door and look at me and wave my cousin saw it and no one else was in house. secondly i was reading my school history to find the reason why the changing rooms where out of bounds and the reson was that a girl had hung herself there and they was going to close the place and build new classrooms well as all people do i broke the rules and went into the changing rooms all of a sudden i saw a girl washing her hands but the water fell straight through her fingers and she turned to me and dissapeared. If you do not believe in ghost or spirits it must be that you do not understand and maybe one day you will experience somerthing strange.
