A squirrel steals something from another one which jumps on the thief's back and clings to it. They are both immobile as the one below won't let go of what it stole, and the one on top won't let go of the thief. I walk by and am astounded that they don't run away. I try to intimidate them by walking closer to them. They turn towards me, still clinging to each other, and they approach me. I get scared of getting fleas from them and go away.
The dream illustrates something I'm going through right now. I was in a relationship where the other person was very clingy. I had to walk away to avoid having this relationship parasitize my life.
