Is it normal that i will sometimes lose control of my body

Sometimes during the day, at school or somewhere in public ill lose control of my own body and it seems like everything is an involuntary movement. I start thinking of so many things in depth that my body sort of functions on its own while I'm thinking much more. To the point where ill start talking to myself and my voice just floats out smoothly like a thought in my head. I appear to be acting normal but after an inconsistency pops up in the actual world my mind snaps back in and I regain control of what I'm dong and feel really spaced out. I feel like I'm just a set of floating eyeballs. Ill sometimes say things like "is this actually happening" or "why am I here". I feel my own imagination is taking over my view in life. To the point Where ill become a danger tco myself and others
