Why did I feel like I had to do this?

I dated this girl for almost a year, and It was an extremely loving and fun relationship, but we broke up because she was a Mormon and I wasn't.
A year passed and I didn't think about her very much, or at least I tried not to.
Anyway, I'm a big race fan, and there was this charity program, if you donated 125 dollars, you would get your name on a racecar. It happened to be for my driver, and I did it right away.
But a few nights after mine was confirmed, I had this extremely weird dream of my ex and the racecar. When I woke up from the dream in the middle of the night, something in the back of my head kept telling me to donate again and have her name on the car. I truly don't understand why.
Why would I feel the need to do this?
