Dremory is the word used to describe somebody's recollection of a drunken night out from the person who can't remembers point of view - if you can't remember it never happened! Dremory!
Friend one- Last night you were so shitfaced you took your pants off and air humped a lamppost!
Friend two, nope, wasn't me, that must have been a dremory!
"Wow, I can't believe how well you remember your dreams. You have such a good dreamory," or "I feel like I'm having de ja vu. Maybe it's just a dreamory."
