Dream About Huge Spider In Kitchen

in the dream I'm standing in the kitchen of a house talking to lupin when I notice alot of movement on the fan In the kitchen. I see it's a huge spider the size of a dinner plate. I watch this spider spin its web back and forth never showing me its back so I can identify it. when it finally drops down a little and is spun around I saw that it was a brown recluse spider. this terrified me so I told lupin we needed to get out of the kitchen and keep Draco and the others out (I'm not sure who else was there in this dream the only people I could see clearly were Draco, lupin and I think I was Luna. so I go out to get an exterminator. and when I come back I check with lupin to make sure no one has been in the kitchen and the spider is gone when I checked the kitchen and I woke up.
