Is the sixth sense real?
Experience (can see them self walking at night using the bathroom return to bed to see themselves laying in the same bed they just left), others can sense something wrong, others can sense a presence. Every one has a Human brain pattern, but others have special Sensitive brain patterns. Or when you visit a place where something bad happen. Like me I can feel something happen (can’t see anything but I get nervous), while some one else can not feel anything. There many things that we don’t have answers too, even if we do have a higher education.
