A dream or nightmare I remember vividly

I was seven. I was hiding behind the chair. The house was dark. It's the aliens. They've taken my family. I come out behind the chair. Looking up the stairs, it's dark. I walk up a bit, the hallway has been transformed into a barren room. It's foggy, dark and empty. Except for a spaceship in the distance and some hay bales (idk). I'm back at the foot of the stairs. I can hear my twin sister, calling out to me from upstairs. She's calling my name. She's calling for help. They have her. They're talking to me. "She's calling to you" (no duh). To the left, the doorway is dark. It's always dark. But a hand reaches out. It's my sister. She's empty. She's reaching out for me, to catch me, to empty me too. I can hear her calling from upstairs, pleading for help, but she's down here with me, her empty shell reaching out for me.

Dude, when you're seven this is a hecka creepy dream.
