Had a dream my ex-boyfriend died?

Last night I had a dream that my ex-boyfriend died. Everyone was mourning his death and there was a big turnout at his funeral. I, however, could've cared less. As the funeral was ending and the people were coming out of the church, I was going in it to get a book out of one of the classrooms. When he was buried, they put the casket in upside-down.

As far as my real life goes, we dated for a month and a half earlier this year. He broke up with me because he didn't want to be in a relationship anymore. We tried to remain friends for several months but he was trying to play head games with me by flirting with me, sending booty texts, and acted like he still wanted to be with me. I was also annoyed with him about how he was always whining about how he couldn't afford to get his car fixed (it needs a $200 part replaced) but was always going to sporting events and amusement parks. Those two things combined is why I stopped talking to him a few months ago. The last time I saw him was a couple months ago when he was shopping at the store I work at. I pretended I didn't notice him.
