Should I use ellipses or two dashes to indicate a pause in speech? I had someone review my first draft and they told me that ellipses are to be used when speech trails off and is left unfinished, such as "I got hit on the head. I don't remember if he was wearing a hat, or..." he said, drifting off into thought. "Come on, you've got to remember or we won't catch the killer!" The reviewer also suggested that I use double dashes to indicate pauses in speech. "The last thing I remember seeing-- well, at least thought I saw-- was this ghostly figure coming at me." Here, the speaker is having a hard time sifting through memories and speaks hesitantly. My concern is that I don't recall ever seeing the use of double dashes in books I've read. When I write it into my dialogue, it appears to me as foreign, and I'm concerned the reader will stop and wonder about it each time, thinking it odd. I do seem to recall the use of ellipses to indicate pauses in speech, and it looks more natural to me on the screen/page, and fades into the text, much like verbal tags, such as "she said." "The last thing I remember seeing... well, at least thought I saw... was this ghostly figure coming at me."
