Murdered by the devil???

Date: 9/20/2018

So basically I was texting a friend and I sorta knew them even though they were new. And then I asked em to come over and we hung out and it was fun. Then later she suggested we went shopping and so we went to the book store but she started suggesting really inappropriate books I knew my parent should not like and that I shouldn’t even read, but I was like so caught up in the moment and she was my friend I didn’t wanna say no so I bought them. I can’t exactly remember now but I also think she used my moms credit card and I again said nothing. When we got home we chilled on opposite ends of the couch when I got a text from my mom. It said “don’t text that number I gave you, it’s not a real number” “Don’t text it Ella” And I saw her out of the corner of my eye go still. Her back to me. I replied “Mom I already texted.” “Mom the person is at my house” “Mom they’re right here” As I texted I heard the friend whisper what I typed even though her back was turned I was getting the chills now. And then out of the corner of my eye still I saw her slowly turn around and stare at me with a deadly expression. Then I woke up but for some reason I just knew that: 1) this friend wasn’t actually somebody I knew, but the devil disguised as a friend. Idk how but that immediately came to me. 2) that she would have killed me if i hadn’t have woken up. It scared me a lot and I’m not sure what to do? I have nightmares that are pretty creepy since I’m a weirdo but this has been by far the creepiest (maybe the second creepiest but the meaning was scary.) I tried googling nothing came up. I haven’t read any books or watched any movies similar in any way. Anybody have any ideas?
