No - no it was not. "Halloween" is a neo-pagan-consumerism creation of the commercial machine. Animism: the belief that the spirits of ancestors or loved ones that had passed on, lingered or returned in the form of objects of nature, e.g. trees, animals, the wind, etc - and were sometimes then reproduced as idols, such as totem poles...this is where the practice of wearing 'costumes' first came from.

And no different than the notion that so-called 'saints' (ie; dead notable Christian faithful) are in some sort of conscious state from which they can interact w/, and on behalf of, God's living faithful.

The Bible clearly refers to 'saints' as the *living* faithful while on the other hand clearly teaching the dead have no part in this world.

"For the living know that they shall die: but the dead know not any thing, neither have they any more a reward; for the memory of them is forgotten.

Also their love, and their hatred, and their envy, is now perished; neither have they any more a portion for ever in any thing that is done under the sun." Ecc9:5-6

And so these 'spirits' that are worshipped and/or interacted with by both pagans AND Christians (in the form of 'saints' and 'dearly departed grannies' 'looking down from heaven' 'watching over' their beloved family) are in fact demons.
