What does it mean when your dream is infested with lizards?

Last night I had a dream that there were a lot of lizards outside of the house. My boyfriend's parents, my boyfriend and I were all inside talking about the lizards and how we hoped they didn't start coming into the house. After a what is now a very fuzzy memory in the dream, lizards started appearing inside the house. There was one on the floor, on the walls, and ceiling. There were maybe four or five total. I woke up as everyone else in the dream was working on getting them out of the house with the fear of the lizards in the dream feeling too real. =/ Is this something to worry about or just a random dream?
