If a dream can tell the future it can also thwart that future. For God will not permit that we shall know what is to come. He is bound to no one that the world unfold just so upon its course and those who by some sorcery or by some dream might come to pierce the veil that lies so darkly over all that is before them may serve by just that vision to cause that God should wrench the world from its heading and set it upon another course altogether and then where stands the sorcerer? Where the dreamer and his dream?
