That dream about waiting in line

There was that dream where I was waiting in line but I had no idea what I was waiting for and I didn't want to ask the guy in front of me because it was Abraham Lincoln and who wants to look stupid in front of Abraham Lincoln so I turned around to ask the guy behind me but it was kind of a similar problem because Genghis Khan probably only spoke Mongolian but I found out that he was a Star Trek fan because anytime you find yourself in front of Genghis Khan it is mandatory to do the Captain Kirk "Kahn!" thing with your hands in the air and Genghis smiled and gave me the live long and prosper sign but immediately contradicted his wish by chopping my head off and that's when I woke up, so I never did find out what the line was for.
