Upset over an argument

Hello

I was wondering if this has happened to any of you before and if so, why?

In my dream I got into an argument with a young man, I don't know who he is I can't really remember apart from the fact that he had blond hair. We were arguing and I felt guilty about it but my alarm went off waking me up before I got chance to make it up.

I really wanted to try and go back to that dream and make things right but I couldn't as I had to get up and do things but it's been bothering me all day, put me in a foul mood with people around me and it seems silly all over a dream.

A thought crossed my mind that maybe it was a past life or a different realm etc but I'm not sure, I've posted this in dreaming already but thought maybe anyone on here maybe able to help aswell

Thanks
