In my country we do not celebrate that day. We have a similar holiday originating from our pagan roots. Dziady - because that's how this custom was called was celebrated in the night of 31 October. As in the case of Halloween it was about living communion with the dead.
As part of the Dziady arriving at "this world" souls had to accommodate to secure their favor and at the same time help them achieve peace in the afterlife.
There is also Samhain - the main Celtic festival, whose name means the end of summer (same e Fuin). It is associated with the end of the harvest and the year according to the Celtic calendar (today conventionally 31 October / 1 November).
I hope you like it.
