Is it worthwhile in any individual case to look for the meaning of a dream, supposing that dreams have any meaning at all and that this meaning can be proved?
The psyche is the most baffling phenomenon with which the scientific mind has ever had to deal. Although we must assume that all psychic phenomena are somehow, in the broadest sense, causally dependent, remember that causality is no more than a statistical truth.
If the space terms predominate in the expression for the interval between event-points, the interval is said to be space-like, since it is then possible to select a co-ordinate system–belonging to an observer with an admissible velocity, in which the events appear simultaneous, and therefore separated only spatially.
If, however, the interval is time-like the events cannot be simultaneous in any co-ordinate system, but there exists a co-ordinate system in which the space terms will vanish entirely, so that the separation between events will be purely temporal, id est, occurring at the same place, but at different times.
