Yes

Sam turned around and saw a blob of what looked like molten glass about as tall as her about 6 feet away. She watched in curiosity as the blob began to shift and retract until the shape was more akin to a 6' tall woman. Her breasts puffed in and out, seemingly trying to find the correct size and soon stopped around a C-cup. The woman's mid section started to tone out and a loose jacket soon became visible too. As the shape began to create her hair, it hit Sam what she was looking at. The shape was emulating her.

"You're coping me, aren't you?" Sam asked.

The shape formed tasty lips and said, "You're...Me...Me...You?"

"Wait are you trying to say that we are the same?" Sam questioned.

A silvery stary tongue slipped out of it's mouth and licked it's newly formed lips, "We...Are...The...Same?"

Driven more by curiosity than fear, Sam's inquisitive mind took over and she walked up towards her mirror image. The shape stood still as it worked out it's legs to match Sam's. Sam looked her up and down, appreciating what others see when they look at her. As she thought to herself she made her way back around the shape to her front side. Her face was more defined and was beginning to gain color, but still maintained a translucent quality to it.

Sam looked downward from her own face, seeing a faithful copy of her leather jacket and shirt underneath. As she continued downward she saw the same jeans form themselves onto her mirror's legs.

Soon the shape finished molding itself and looked exactly like Sam, except with a translucent sheen to her, like she was made out of glass.

Sam reached a hand out toward her mirror's face, "Why did you make yourself look like me? What are you?"

"You make me look like you," the mirror responded, "What are you?"

Sam touched the face of her mirror, it felt warm and solid, "I'm me, Sam. Do you have a name?"

"Sam make me...Sam make name?" She said, tilting her head into Sam's hand.

"Um" Sam was confused, but understood her mirror's request "How about Alice?" It seemed fitting for a person shaped looking glass.

"I'm Alice" Alice responded
