What is deja vu, but a sense of having been somewhere before. The subconscious forgets nothing and can recreate every sense received by the central nervous system (except for pain...that's forgotten; had to be, or women would give birth only once otherwise). In Sand Soldier, patterns that began as a child are found to repeat twice more in later life, each time having deeper, and more dangerous, circumstances. Are they deepening of lessons started as a preschooler, or repeated warnings to change his path before it's too late?
