anonymous nightmare

I have been having weird dreams for the past few days, and I don't remember any one of them. This morning I woke up to a nightmare, and it stayed in my head, it was so clear it shocked me. It was like one of those M. Night shyamalan movies where the 'thing' that was after me never revealed itself. It was dark, I was hiding out at home.. Doors and windows all locked.. Then suddenly I saw that the door was open. no one was near the door, it would seem like it opened by itself. I began shouting, who the fuck opened the door! close it! damn it, close it! ~

I woke up to my phone vibrating on my table, but I didn't move a muscle. I was wide awake, I knew I just had a nightmare and was still pretty shaken up about it.

After a couple of seconds laying still, the noise was starting to annoy me. I got up and grabbed my phone. Who the hell would call me at this time? I thought it must have been about 5 am in the morning. The curtains were drawn and I didn't realize that the sun was rising, it was 7. I looked at my phone and saw that it was an unknown number. I never answered.
