Which word means your lookalike or double?

its midnight and a friend who sleepby sees a ghost look a like my daughter but my daughter is still in bed still she's not scared

toothless beachrat, I have one of those faces too.

My mom once got up and walked across a restaurant to ask a guy, "what, you can't come say hi to your mom"? As she thought it was me. It wasn't due to old age, she was about 50 when it happened. I've had people swear I'm someone they grew up with when they were younger. I guess I just have "one of those faces"!
