Dream of classmate

I had a dream of a classmate who had died in a car accident a few years ago, I think 2015.

Now what I find odd was that I even dreamt of this person because we were never friends & didn't talk to each other, only in instances we happened to be sitting near each other & even then it was rare & very minimal. He wasn't someone I've thought of at all after high school or even during to be honest.

The really weird part is that I happened to have had the dream practically on the eve of the anniversary of his death.

I woke up just feeling sad, & stayed sad all day, even cried a bit when I saw the date he died & how old he was (22). Just spent the whole day questioning why, if it were any other day I had the dream I wouldn't be questioning it as much as I am. It's too close to date of his passing & for me of all people to be dreaming it at all is what makes it all odd.
