I sometimes want to be doctor doom
How do you plan to be Doctor Doom?
I would say "I wish I could be doctor doom" and then I would fulfill my wish
It's cool you have a good imagination. Most people wish they are some kind of fictional character with superpowers. Just don't let fantasy consume you because at the end of the day superpowers in comic books don't exist and you don't want to let it cause mental issues.
I like to use my imagination. I also have been using "Hail Hydra" as my catchphrase with my buddy Steve.
It is good to have fun especially with friends.
