Patient faces that quietly admonish

Last night I had a dream. I must have been in a car and passed what I knew was an abattoir. A dark and deep foreboding possessed me and shortly after driving past I saw a livestock lorry up ahead. I didn’t want to look at the lorry in case I saw the animals but felt compelled to do so. I was relieved that even though I could see in the back of the lorry no animals were visible.
