A disturbing dream

I had a disturbing dream last night.
About someone having sex with someone.
It was so vivid!
The last time I had this dream was way back in grade 5.
I dreamt that the son of my landlady (married) had sex with someone.
A few weeks later, the woman living in the other room had a miscarriage, and guess who was the father!!!
They were having an affair.
Now I wonder who is it this time...
