Halloween is fundamentally a witch's holiday opposed to the resurrection. It is the day on which "the veil between the worlds is thin", and people with the sight see the spirits of the dead. Witches have metaphysical opinions, and one is that life, death and rebirth are a cycle, it is the cycle of reincarnation. The intermediary period between death and rebirth in their metaphysics is called bardo or pardo, from Tibetan (The Tibetan Book of the Dead). Halloween is considered the day to consult a spirit medium for an oracle, or prediction of the future, Saul Samuel and Witch of Endor style.
Halloween is a philosophically undesirable holiday, it denies the syllogistic logic of Aristotle, who divided everything into good and evil. Syllogistically speaking, it commits the fallacy of the excluded middle term (in a three-line syllogism), it embraces a belief in death and rebirth without a diacritical moral judgement phase.
