mystifixation
an obsessive desire to present even obvious things as mysterious ones and thus making them unclear and hard to understand just to gain attention of the listeners (from mystification + fixation)
I asked Jeremy about his plans for summer holidays, but I got lost after a couple of seconds he started talking, because he made it so confidential and difficult to understand. It's his mystifixation - a desire to make everything, even simple things, look and sound mysterious.
