Dream About Son Girlfriend Intimacy

We were in a two story house and my 15 year old son had a girlfriend I was busy downstairs cleaning and they went upstairs, when I went up to check on them they were being intimate and I got mad at my son for fornicating, I began to beat up the girl and slam her head into the floor but she didn’t care and my son was so rude and disrespectful to me I couldn’t believe how rude he was to me as he mocked me, I was trying to explain that he was too young to do that and he would just stare at me and mock me, so I called up my husband and asked him to discipline my son. It broke my heart that my son would be so angry at me.
