Halloween wasn't something we celebrated in Sweden when I grew up (we did something similar at Easter where we dressed up as witches/old ladies), and it wasn't even particularly here in the UK either, but in the past few years it's become very popular. And I for one appreciate any sort of break from the everyday dreariness that envelopes us at this time of year. For several days before, Oomoo (who for the second year running dressed up as a cat) was so excited about going trick or treating with his cousins and on the night we all had great fun. Luckily he's already forgotten about his big bag of sweetie swag :)
P.S. How creepy is that witch in the fifth picture?? Answer: very. She opened the door like that and then continued to cackle until each trick or treater had left.
