Is it normal that i usually really overthink about something

When I want to do something, I usually always blank stare, walk left-right, or walk in circles, then I make sounds, my hands shake, and I uncontrollably think about things. They are usually just violence, sword fights, railguns, detonations, satisfying things, happy situations, loving people, dreamworld, or even just (somehow) extremely efficient rocket propulsion that can reach escape velocity in just a few minutes.
