Weird part of a dream

Date: 11/21/2016

I heard noises outside my house so I ran downstairs as quick as possible to my mom being confused. Then it happened again and I said somebody is coming in. I had a thought that it might be my dad but then he ran downstairs alarmed and the door busted open and it was a doppelganger of my dad but he had a weird face and he turned around and looked at me and it scared me awake instantly.
