Giant Spider Made of Dust Zombies

I haven't remembered a dream in a while.  Part of that I think was my trip home for the holidays and just sleeping in unfamiliar territory.  I still don't recall this one very well, but here it is...

We, my husband and I, were at home visiting my parents and siblings and friends from back home.  But there was this big, about 6 foot long black snake with a huge head and moved super fast that kept following Brad and me.  My parents kept telling me that it was no problem, that even though it was a highly poisonous and dangerous snake, it was their pet and that I shouldn't worry.  This snake would slither up walls so fast to get at us that it was almost like it was flying.  Luckily, Kayla (my youngest sister's best friend) would always catch it by the head before it got to Naomi (our daughter) to eat her.  One time, she caught it, and it opened its mouth and it was full of dirt and ash that just kept spilling out every where.  It was chomping and hissing at us.  We didn't feel safe, so we left and went to a family friends house.

At her house, we were told the room we were going to sleep in was in the basement.  We open the door down to the basement and find that there are no stairs down, but instead, we must jump down into this mamouth sized spider looking thing.  As we jump down, I realize that it's not a giant spider at all; it's a bunch of zombies standing on each other in weird ways to make it look like a giant spider.  As we land on the spider made of zombies, they turn to dust. (Side note: at this point in my dream, I'm observing it like watching a movie, I can see myself jump and the dust billowing out, almost like in a scene from Mummy or Prince of Persia or something like that.  When we were at my parent's house, I was dreaming in "real mode" where I felt like myself, saw things as I normally see, etc.)  We must whack at all the zombies to get to our bed, and eventually we get there just fine.  But it's floating on water and apparently, my "guardian zombie" decided to abandon protecting me, so all the other zombies start stealing things from us-- like my wedding rings, and Brad's glasses, my daughter's diapers.  We must kill all of the zombies, including my "guardian zombie" so that the water will go away that under our bed and i can get my little stolen treasures, which are hidden under the bed.

Eventually it's done, we get my rings and brad's glasses and the diapers, which are covered in this orange poopy substance, so we leave those behind and plan to go buy more asap.  After wards, ensues a discussion, upstairs in the normal house, NOT in the freaky basement, about who can use a car to go to the store and if we can because it's the Sabbath.

This is about where I wake up.
Any thoughts on what this could mean?
