Dream of children, hands

My cat wakes me up At 630am to go outside. My oldest son happens to be at the side of the bed so I take his hand and then my youngest son is there and I take his hand. I hear a loud airplane noise. We walk to the front door and I notice its open. I procede to open it to let the cat out and see my husband on the porch and realize he left the door ajar. Walking back through the house with both children holding my hands we look out the window and a plane flies over the house and crashes into the town below.
