Most of you guys have an wrong idea about ghosts,demons,djinns or any stuff that can haunt or scare,simply because your only base is the movie Paranormal Activity.
There are maybe 1.000.000 reasons for the remote to be there,like,it fell or something.Don't be scared with something silly.
A ghost almost never haunts(only the angered ones,that have lived an extremely painful life),a djinn always haunts,but never attacks,and a demon(oh boy)these can kill you when angered.
(i know ,because i always see dead people.Not like in the movies or cartoons,i only see an very weak shadow,sometimes normal,sometimes with an strange flame on their hands...only an gray image or face,the eyes have an extremely weak shine,that resembles an cat's eye in the darkness)
