Do you ever dream of your favourite characters (written by you or others)?
I can't say I do. I'm also relieved about that. I can think of several of my own characters who I don't want to meet in any kind of alley. I certainly don't want them haunting me at night either!
Where I DO dream of characters is in hoping they have the impact on a potential reader I set out to achieve. It's not really for me to say whether that works or not, only the reader can know. All I can do is give it my best shot.
When reading works by other writers, the ones that stay with me the most are the ones where the characters have the most impact. So that inspires me with my own writing. I'm still glad they don't disturb my sleep pattern though! (I would not be a happy bunny...!).
I do a lot of my reading at bedtime so I did wonder if I would have strange dreams based on whatever it was I was reading. Hasn't happened at all. Given I read fantasy, crime, historical, and a good range of non-fiction books, it is just as well. I think some very strange images would be conjured up.
