ANYway...
One of the strange but interesting things about dreams is how the mind will dredge up the smallest, briefest image from the back of your brain and build a narrative around it.
A while back I had this fairly mundane dream where I helped a very attractive woman unload groceries from her car and bring them into her house. Then we had beverages on her couch.
I recognized the woman in the dream from somewhere, but it took me MONTHS to figure out who she was and where I'd seen her.
Turns out she's Samia Shoaib, who I've only ever seen in her brief appearance in "The Sixth Sense" where she's buying a ring with Shayamalan's self-insert character.
