Had a dream where in the dream I realized I was in a dream world. My brother and I were coming back from the store while walking up to the house I see a gas station and say to myself "I must be in the dream world, I wonder if I buy a lottery ticket will it appear when I wake up". So before I go into the store I walk around a bit to see if anything is familiar but now I encounter a man with a small black dog. The dog is staring me down as the guy is trying to hold the dog back. The dog breaks loose and clamps down on the inside of my left wrist. I get the dog off with my right hand The guy is apologizing in a panic. There is no blood coming out or pain.Next thing is there are maybe three other people around and now the dog is tied up in this box, something like a six pack of beer box hanging on like a zip-line sort of thing. The dog is growling at me. One of the people there gives me a knife. Someone else says, don't stab the dog yet and hands me a very flimsy straight razor. The straight razor just flops around. The dog senses this and is about to attack again when someone sticks a knife up the box and stabs the dog.The dog calms down as I go to the front of the building, but as I look on the side of the building I can only see the back of the box with a hand pulling the knife out and tosses it in my direction where I see the blood all over the knife. Then I wake up.
