Yes, 100%. It's not just "possible"... you're describing exactly what ADHD is like for me. This is one reason why I didn't seek an ADHD diagnosis until later on in life. I didn't understand that it was possible to have ADHD and also be able to "hyperfocus" on certain things.

It's also why I think ADHD is such a badly named condition. You don't have an attention deficit you have an attention regulation deficit - which means sometimes you can have a surplus of attention which you (often) cannot control.
