Dream = "Dreams are sequence images, sounds and feelings experienced while sleeping, strongly associated with rapid eye movement sleep." -Wikipedia
Diary = "A diary is a record (originally in written book format) with discrete entries arranged by date reporting on what has happened over the course of a day or other period."
Hence, dream diary is a diary for the dreams. A place to write down your dreams. I did this to better remember my dreams. They are wacky and hilarious at times... and sometimes rather disturbing.
Like I've had dreams in which I've been a Dexter-like serial killer. I've killed people, hid their bodies and been very stressed about whether the bodies be found, and what would become of me if I'd get caught. It would be unfair to lock me away for years, especially since it won't bring the dead people back. Wasting just another life won't help anyone.
There are no faster fingerslingers than us, the SJs.
