Odd Pee Dream Last Night

I've never been much turned on by pee (not a turn off either) but last night I had a dream that still has me thinking about it hours later.

In the dream I was in a pond with a bunch of friends including an ex girlfriend (fifteen years ex and both of us happily married elsewhere). There was nothing odd going on until she comes up to me in the pond and with hands on my shoulders and facing me. There was some flirty discussion, dream logic, I don't know what but that was the feeling, and as she hugs me before leaving she asks if I can feel the warmth. I can and know just what it is. She smiles and tells me she'd always wanted me to feel that. In the dream she was happy and I was happy.

This never came up in any regard as we were dating. I'm very surprised by dream and this seemed liked the most comfortable place to share. Thanks for "listening."
