What is the point of Halloween?

[Tigermoth]

Christmas - good cheer/ special family time/ winter solstice/ pagan ritual/ christian festival etc

Easter - beginning of spring/pagan ritual/ christian festival etc

November 5th - gunpowder, treason and plot/beginning of autumn/ fireworks etc

Halloween - the witches ghosts and ghouls come out/ And?

Is there any good reason to celebrate Halloween, and if so, how? When I grew up, no child played trick or treat or put on fancy dress. I just cannot get my head round these activities. For the sake of my sons can someone please explain.
