If you dreamt something bad, would it make you feel guilty?

Last night I dreamt that I was about to cheat on my boyfriend. I had organised to meet up with someone, but my boyfriend came home early.

I told him about my dream and I have apologised nearly all day for it. He says I shouldn’t apologise for something I had no control over and that it was just a dream. I feel really awful though, it’s been on my mind all day and I feel really guilty

Would you feel bad, or not care either way?
