DD was in the care of someone else and DH and I were at home with DS. He all of a sudden had the virus from I Am Legend, making him a zombie who tried to kill us. He was highly contagious and we had DD to think about so we had to throw him in a room (so he couldn't attack us) and lock him in. And leave him, forever as far as we knew.
The worst part was hearing him play with toys as we walked away and him sounding perfectly happy and normal but we knew he wasn't. DH and I both almost went back for him.
I'd be so happy if I never have another dream like that again.
