Greetings,

I have never seen a ghost before, nor have i had any strange occurrences happen to me.
However, some friends and family members whom are sincere swear that they have seen "ghosts" in their house. Windows opening by themselves, depressions in chairs, lights turning on and off, actually seeing figures in rooms, cats refusing to enter certain rooms, objects being moved. The reason I believe them is because they are honest and are not the type to deceive me. I believe that they experienced something but not because they saw a ghost or objects moved. EM fields have been shown to alter the perception of the brain (ie. https://en.wikipedia.org/wiki/God_helmet)
Also this could be the cause of delusion or hallucination from malfunctioning part of the brain.

Does anyone have any opinions?
