The former refer to what actually is, has happened or will occur with or without one's own contribution. On the borderline between the real 4 and the unreal 4 representations lie hunches about possibilities and plans for the future. The realness of representations can also change. Ordinary memories do not have any quality of illusoriness. The degree of realness can vary all the more among representations.
Several factors account for greater or lesser realness of a representation.
Two of these are temporal and spatial distance. Correspondingly, a fire in another part of town is more real 4 than one in a distant city - unless one is more familiar with the respective area in the distant city than with the part of one's town where the fire is. Thus, familiarity is a third factor accounting for realness. Still another factor bearing upon the degree of realness of specifically past events is whether or not they still exert effects upon present happenings. The realness of future events depends correspondingly on the certainty or improbability of their occurring.
