Is it normal when I'm alone, I act like a secret agent assassin?

I do something similar every now and then. When I was kid I would often pretend to be some spy working with a supercomputer trying to find important information. I would would talk to the people (agents) I worked with on a gigantic screen and we would talk about missions and personal stuff depending on who it was. I would sometimes pretend to be someone of importance who worked in a office. When in private I would work and think about personal stuff and call people up. Then, if the secretary knocked on my door I would have to put personally stuff aside and become professional before my client came in. When the client came in we would talk about talk about their needs and what I could do for them. Occasionally, my boss would come in for a chat.

I'm sure I had many more "fantasies" than these but these are the ones that really stand out the most. I also remember having a fantasy about Digimon Frontier and we were doing something and I had to type on my supercomputer (desk). Basically, I think I took on the role Digidestined Izzy had in the first series.
