That's what I believed, but for your comment I thought it might be different. Here there are some special sweets for this time depending on the area. They make "huesos de santo" (saint bones) and "panellets" (small cookie-like sweets made of almond flour) for this defuncts day. Tomorrow most Christian believers will go to the cemetery to pay respect to their dead beloved ones. Here there was no tradition of dressing customs, nor going over the neighborhood houses doors asking the trick or treat thing, but kids by seeing it in the movies and TV series, have been doing that for the last 5-10 years. Now they even sell plastic pumpkins at the department stores
