[ME] Something happened this morning that made me not want to sleep.

This is my first time posting here, so I'll try to be concise. To give some background I live in a semi rural area with a lot of woods and wheat fields. That being said, there are a lot of coyotes, owls, and the normal animals you would assume. It started at 11:56 last night on the way to a good friends house. I felt slightly off on the way there, but ignored it. As soon as I pulled up into his driveway the feeling that was rising up in my gut was now undeniable. Again, I tried to push it aside. He invites me in and we go upstairs to hang out and play music. The night was pretty average, and it winded down about 2:45 A.M. Now, this particular friend happens to be Navajo, and has frequently told me he has a 'Spirit' that lives in his room. I believe him but I've never really gave it any thought till I decided to leave. As I was saying my good byes chills started to run down my back. That's when it started to change. As I was driving home I felt as if I was being followed. I caught my self looking around and checking behind me inside my car paranoid that someone was with me. I arrived at my house at approximately 3:15 A.M. and promptly went inside given the creepiness that my buddy had left me with. I went inside and undressed, ready to go to sleep. I lulled off without a hitch. My dream started off pretty calmly, then changed at the very end. In the end of the dream me and my buddy had been driving in his car when all of a sudden this white human/dog came out of nowhere and smashed into the side of the car. I closed my eyes and heard my friend cry and scream 'IT'S A WALKER.' I jolted up from sleep and felt extremely cold, and scared. I KNEW something was watching me, but I didn't know where. I have never had an experience like this and I feel very unsettled. I just wanted to share with y'all.
