I don't dream about TLK anymore, really
It's a shame, cause I did a lot when I was younger. I seemed to have a lot of nightmares when I was very young, so they were a bit of a merciful relief TBH.
That being said, my most successful fanfic to date, "Captive", was heavily influenced by a pretty vivid TLK dream I had a few months before I started writing it...
