I'm slowly picking up writing again, but I've run into an old time-honoured tradition of mine; obsessing over certain characters. To me, my characters are as real as real-life people; they have their own personalities, likes/dislikes, manners of speech, body language and so on. Unfortunately, some of them also tend to get stuck in my mind and I hyper-fixate on them to the point where they overshadow the rest of the cast. To be clear, I'm not imagining myself hanging out with them or anything, just what they do in the plot itself; it's a bit like watching movie clips on re-run but out of order. Sometimes I wish I could just put those characters into a locked box and focus on other parts of the story. I tend to daydream a lot so that doesn't really help the problem.

Any other writers who have or have had issues with characters who won't leave them alone? What would you suggest to someone in a similar predicament?
