I had a nightmare last night. In the nightmare I was dozing off in the beach yard of a house. (Something like the yard on Lake Tapps that thefanciest's parents have.) And then then the people in the next yard over were killed by an invisible murderer who looked over at me as he was doing it.
And then I woke up yelling help.
I immediately knew it was a dream. But I generally don't remember dreams. And I generally don't have actual terrifying nightmares. So it was weird.
