On All Hallows’ Eve, when the veil between the worlds of the living and the dead is at its thinnest, ghosts come out, sometimes in small groups. While the bigger ghosts get up to more serious hauntings, these spooky spirits float around, getting up to mischievous acts and scaring trick-or-treaters. But once Halloween is over, these little specters fly off back to the land of the dead, ready to escape once more next year. Light up your for Halloween with this delightfully spooky trio.What’s the right word for a group of ghosts anyway? A pack? A congress? A coven? A gaggle? A murder? A fright? A haunt? We didn’t know, so we just called this Small Ghostly Group, but if you get the chance to ask any ghosts, let us know what you hear back. Three’s company! All the best things come in threes, and small ghosts are no different.
