Is it normal to have a dream like this?

If it happens again i'll definatly try to find out wahat it means and yeah I do watch horror films sometimes but they never really scare me. Something good has come from this though. I have always written novellas and ive taken a cue from the woman and I'm turning it into a short story. I think this has the potential to be quite good. I haven't had any new ideas to write about in a long time. I think a tiny part of me wants them to carry on for new ideas
