At night, I suddenly saw a blackbird flying at home, but it was gone again. It's true' I never believe in evil, but what is this? my family

Just now, I was awakened by the barking of dogs at home. I opened the door and went out. I thought they were thirsty. After I fed them water, I turned around and just wanted to go back to my room to sleep when I saw a bird! It's a bird! A bird as big as a crow! ! ! I'm not mistaken! I opened the screen window and let it fly out! But it flapped its wings back and forth in my house, flew three or four times around the living room (the dog at home was barking) and landed on the wine cabinet against the wall! I hurried to knock on my mother's door, and when we looked again, the door was gone! ! Not a trace! ! ! ! I'm not dreaming! ! ! ! ! There are really birds! ! ! ! ! My mother doesn't believe me! ! ! There are really birds! ! !
