Same dream every halloween night?

every year the night before halloween i have the same dream. me, my mom, dad, and sister are all in our living room, and im playing with a sky dancer(a toy i used to have when i was like 6, it has a base and a flying fairy. in the dream it even had the chewed on wing-it really had one on the real toy). then a witch, vampire, and a werewolf come out of the kitchen, trying to take the base of the skydancer. they take it and then say that we have 1 hour to hide the fairy dancer part. so we go on and then in exactally one hour they are back, while we run around trying to hide it. we always end up hiding it in out unfinished basement in the chimney for our to-be fireplace. but inside it is an alligator. so we get it hidded and when they look for it-the alligator eats them, and I get the base part back. then i wake up. it has happened every year since 2001(i was 11). what does it mean?
