Sexy dreams? About someone else?

On a scale of 1-10 how inappropriate is it to have a sexy dream about a co-worker?

And if you know said co-worker's wife/husband/partner, how inappropriate is it to tell their partner (to have a giggle about it)??? It seems wildly inappropriate to mention it to anyone else.

Or is it simply wildly inappropriate entirely!?!?
Thoughts?

Boy was it good

Weirdly, I had this dream last night that I had super satisfying sex. With someone else. And on this day of all days!
It was hot though... Is this being unfaithful? Dreaming about some mystery dream man and having super hot sex? Or is it simply because I haven't had sex and now that it's so close it's manifesting in my nocturnal brain.....
I had that thing where you wake up and you'd jump anything that was there at the time. Thankfully Pix was in the other room (too far?)
