Having sex with your mother in a dream symbolizes compromised boundaries, a perverted heart, or might be a call to rethink of how you relate to each other or may pertain to an aspect of your relationship.
A mother represents a caring and nurturing character in your life as she carried you in her womb for nine months and has nurtured you this far.
The dream can have several meanings depending on the setting. For example, a lady wrote to me saying she had a sex dream with her son. She explained how she was currently going through financial struggles due to joblessness for several years and her son was going through depression/ demonic oppression; hence, it was a stressful period for them.
She also added that before going to bed she had prayed over her son, and her troubles, and particularly prayed and asked the Lord to reveal the truth about her life and circumstances.
This was her dream.
In the dream, I was having sex with my son and at some point, he asked me to kiss him I refused and told him to go get a girlfriend. I then said to him I wonder what God thinks of what we are doing and he just laughed. Then I realized we were in the house I was brought up in, in one of the bedrooms.
As we were having sex I saw a stranger enter another bedroom so I pushed off my son and I got off the bed to see who the person was. By now, he was back in the living room. In the sitting room there was a group of one family ( men, women and children, and youth).
I asked them who they were and what they wanted in my house. They said they were waiting for another relative to arrive because they had something they needed me to know. They were arrogant and even got up to put on the TV, acting as though they had a right in the house. The dream ended before they could tell me why they were there.Anonymous
In this case, the dream was symbolic. The sex imagery reflected the unusual events- (the financial challenges and depression)- that were happening in their lives, just as the intimacy with her son is an unthinkable event.
The strangers in the dream symbolized these unwelcome circumstances that were tormenting them. This family is experiencing spiritual warfare.
The person she saw as her son might also be a demonic spirit that has taken the image of her son. The devil is a shape-shifter and disguises himself to manipulate people. We see him turning into a dragon in revelation, and his fallen angels turning into men to sleep with women in Genesis 6.
Your mother forcing you to have sex in a dream
The dream implies she is forcing you to take up character traits you are not comfortable with. Or in other words, she has become too involved in your affairs until she feels she has control over everything you do, hence overpowering. This act is greatly condemned in the scriptures.
It might also be an evil dream if you are living in sin.
“You shall not uncover the nakedness of your father, which is the nakedness of your mother; she is your mother, you shall not uncover her nakedness. You shall not uncover the nakedness of your father's wife; it is your father's nakedness.” Leviticus 18:7-8, ESV
Being intimate with your mother in a dream
The symbolism in this context means that you are going to reconcile with her if you had previous issues, and also you are going to have a better and strong relationship and friendship with her.
It may also mean there are various aspects of your mother’s character you admire, such as her strength, calmness, kindness, etc. This is what your dream is trying to convey using sex imagery.
