I agree that some background would be good, but you don't have to give it. I'm also available for PMs and I've gone through phases where my dreams have been less than desirable. Also, do you exercise during the day? I don't know how true it is for everyone, but I've heard that physical exertion can cause you to sleep more heavily, making your REM cycles shorter. I'm not sure if that's completely true, but I think it might have some validity.
