Search Results: having sex with girlfriend

I went out a few times with my coworker in 2015. As promising as the relationship was, I broke it off because I didn't feel I was ready for a new relationship, because I wasn't over my first girlfriend, even though we broke up a year prior.
It became an easier decision when she told me she still lived with her ex. But she made it awkward as hell at work. But she quit a few months later.
Fast forward to June 2016, she comes back to work and she holds a grudge against me. Especially since I got back together with my original girlfriend.
I left in August of 2016 and in in December of 2016, my girlfriend and I were having issues and the co-worker called me up one night, and asked if I'd hang out and have sex with her before she moved home the next day. Even though my girlfriend was leaving for a mission and our breakup was inevitable, I didn't do it.
But in early 2017, the co-worker and I started talking regularly and talked about everything that happened. But then she started trying to convert me to the Mormon church and that was the same religion my ex was a part of and I wasn't Mormon.
I blocked and didn't say absolutely anything to the co-worker from that point on.
Last year, I made a new Facebook, and the co-worker never came up during that time.
Last night, I had this very unusual dream where I met up with the co-worker and we worked things out and all that.
Today, I'm on Facebook and she came up as a friend suggestion, with 0 mutual friends and I used a new email and no phone number when I made this Facebook. In addition to that, all I have to do is type 'n' and she is the first result on my search and I never searched her once.
Like I said, it's been almost two years since we last spoke and she hasn't come up whatsoever in this Facebook 8n the year I've had it.

This has really thrown me for a loop and I haven't even thought about her since we stopped talking.

Is this a coincidence or more than that?
