Take a closer look. It is just a good-bye from Halloween!
Here is a 'normal' version of the text. (If you got interested in how I did it, here is the link to a very simple tool - Flip Text.)

Trick-or-treating is a customary celebration for children on Halloween. Children go in costumes from house to house, asking for treats such as candy or sometimes money, with the question, "Trick or treat?" The word "trick" refers to a (mostly idle) threat to perform mischief on the homeowners or their property if no treat is given. In some parts of Ireland and Scotland children still go guising. In this custom the child performs some sort of show, i.e. sings a song or tells a ghost story, in order to earn their treats.

On Halloween night I had some unexpected guests in disguise, I did not recognise anyone but they must have known where I lived. Luckily, I had prepared a bowl of sweets beforehand, so I treated them and was spared tricking but got thanks instead!
