My sister Petra, who is a young teenager in this dream, and her husband David who is his real age, have found some sort of large lizard, several feet in length. They are telling me how it is sick, and they are going to capture it and take care of it. Their plan doesn't seem like a very good idea, though; they are going to wrap some sort of cord around it like a leash and pull it, and I am concerned that it will wrap too tight and hurt the beast. Besides, they don't know how to take care of sick animals - what makes them think it'll get better at their house? It just seems like a bad idea, and I'm trying to figure out how to explain that to them.
