I kissed another man....

This was a few nights ago and it has been bothering me.

I dreamt I was either at my old home or in a hallway and an old friend of mine was there. We were talking and he somehow started stepping closer to me. I didn’t shy away like I usually would, I don’t normally feel comfortable with people that close to me, only my husband and best friend. But then his face is inches from mine and we kissed. Not chaste one either. Like full blown make out. He had pinned me against a wall and was kissing me hard. Then I woke up. I felt so confused. I felt like I just cheated on my husband. I felt so guilty, confused, and turned on at the same time.

Is this normal?

The guy in my dream is like a brother to me, even though I haven’t seen him since December (different life paths). There was a time I had a crush on him but that was years ago and obviously I moved on and married a man I love deeply. Help?!
