I am very social where I work, interact with customers a lot, talk to my employees, but also keep my personal life to myself. Overall, I am a generally positive person.

However, some days when I am at work I get these "what-if" thoughts and I don't know where they come from.

Example

What if my supervisor and I got into a confrontation over something, I imagine how I would handle it, what it would look like etc.

Or what if I get into a confrontation with a customer/employee over something, how it would play out, what would I say, etc.

Are these negative thought patterns?

What is causing these thoughts to manifest?

What are some things I can do to think more positive?

I really don't understand why I am coming up with these scenarios.

Thoughts?
