not exactly a nightmare, but...

Date: 5/14/2016

It was a warm and sunny late spring evening, and I was walking in a place I haven't been in before, but in the dream I seemed to know it. I was with my phone. Suddenly I saw a suspicious-looking man walking toward me and glaring at me weirdly. When he was next to me, I accidentally dropped my phone. With a little gasp, I picked it up and searched for damage. Luckily it was fine. The man had walked few steps away from me, so I thought I was safe and continued walking. However, I heard the man running to me. I panicked and started walking faster, but he kept up with me easily. When I saw his shadow right behind me, I knew it was game over. He sliced my neck open with a knife and ran away. I screamed for help, even though it didn't hurt. I also realized there was no blood coming, but I still screamed. Then I woke up.
