This is my experience with the other side.
I was never a child that created imaginary friends. But since I was 13 I was never alone, something came to me. Something I never saw but I know how he looks when I draw 'him'. I can hear him talk to me, telling me things about people and when I talk about what I heard they will ask me how I knew it. After the first three years I gave him a name, 'Sad'.
The name is odd I know, but whenever I get sad or angry I can feel him banging on the inside to get out, I can feel him below my shoulders and on my back. Only in this past year I struggle to keep him in. I hear him more often and feel him continuously walking around me. Every night I sleep I'm rarely scared because I feel him looking over me, sometimes he sits by my feet or he hangs off my roof. I know my story sounds made up but Sad was always around me and I don't know why, sometimes he takes over and it feels like I'm watching a movie.
When I'm around some people I can feel their 'haunting' around them, some bigger than my shadow and some smaller. Sad gives this feeling of comfort and at some times danger, he is protective over me. When people misuses me or harms me, things happen to them. Nothing right away and not major things. The worst was the one person who broke my heart got a string of bad luck, things breaking or sudden ailments.
There is of course no proof that it is Sad's doing but I can feel his presence around the said person. I just want to know how I came to be bonded with him.
