Dream

I had a dream last night and I can't seem to shake it. All the emotions in the dream were so real. I'm a little afraid as it was not a good dream. I was been accused by family of having feelings and a relation and pregnancy with my brother in-law. The scary part was that in my dream I couldn't defend myself and it seemed like I did have feelings for him. This has unsettled my mind. Please advise me. Should I just read ta'awuz and forget it or is it a reprimand from Allah Ta'ala. Please advise.
