I would answer I don't know if there wasn't this subtle sense that that there is no controller
Perhaps a little explanation of the workings of the mind might assist here.
As we carry on our day-to-day lives, the majority of the time the mind is at rest (unless someone is deeply troubled by something).
When the we are questioned about this 'I', this 'me' we think we are - A person - Then the mind pops up and claims the action or event for itself.
For example, say you go to the cinema to watch a film. I don't know if you've ever considered it, but we become so ethralled and interested in the film that during this process, all there is is experience. The experience of watching and listening. No 'I' doing it. We become so absorbed in the 'now' that the mind stops, and there is no 'I'. No person watching a film - Just the pure direct experience of it.
When a friend questions you later, 'where have you been', the mind pops up and claims the activity for itself 'I have been to the cinema to watch a film'. The 'I' being the body/mind. A person.
Note that the only time 'I' exists is when we think about it. When it is questioned. When we consider future or past activities, or present continuous activities. Without a thought, there is no 'I'!
Perhaps see if this process is true or not in your own experience as we continue our investigation together.
Pick up an object - Any object. Look!
Examine your own direct experience and tell me what picked it up?
What controlled the movements of the hand and arm in the process?
