Lots of things would come to mind. Revenge, sex, regret, frustrations, hope, plans and a lot just used to happen in mind at that time. More than usual. More than it would usually come to my mind.
It's not that they are always on mind, it's not a problem. But at least for meditation you are supposed to be free of such thoughts and even if there's a thought it ought to be only just that thought(not two or more), so that maybe you can meditate just concentrating on that thought and sort of meditate if at all.
Actually I had started that to fight a loss I had suffered.
I gave up. Went to usual life again. Realised it is a loss and no use fighting it. Just accept it. Drink, travel, play, run(I love running and walking) and have fun in whatever way I could. I did that.
It's good now. At least I am not worried now that I need to meditate.
