Yer but the chocolate and delivery mechanic would point more towards mystical than just a simple psychic its too elaborate, too widespread and too untargeted, unless the whole delivery system was a memory manipulation and no one really got the eggs but then that level of magic would have side effects.
The Letter A, well it could be hinting at Semitic derivation of Astarte/Ashtoreth I seem to recall that many suspect the holiday of Easter is loosely derived from her, the egg being a symbol of fertility I'll look into it.
