*SH trigger warning* Dreams and Guilt

So I had this dream and even though I know it's not real I still feel guilty for what I did in it. In the dream my husband and I were at a party but the curtain to the bathrooms entrance kept falling down and I had to go really badly. Anyways so my husband and I are fighting the whole time and he finally just leaves me. Then an old friend of mine comes over and starts talking to me so I ask him to help me put the curtain up so I can go to the bathroom. And he asks me where my husband is and I tell him what happened and he sounded surprised and said,"He just left you?!" And so we talked and then I kissed him! And I told him never to tell anyone else because I know my husband would come back.

I feel ashamed and humiliated and guilty. I know it's not real but it felt real. I guess I feel so guilty because my husband hates this guy in real life and has always thought that me and this friend have a mutual attraction. When I told him about relapsing (cutting) I tried to do it over the phone but couldn't so I told him I'd text him and he actually thought I was leaving him for this friend because I couldn't say it over the phone. *sigh*

Dreams don't mean anything right?!
