Doing unlawful things to your mother in a dream

Assalamu alikum, I’ve been having dreams about my mother where i touch her forbidden parts and ejaculate in my sleep, waking up disgusted by it. In the dream I don’t usually or infact never seen her face clearly but i get the feeling that it’s my mother. She is not responsive when i touch her; meaning she doesn’t seem to like it or hate it. Of the 2 dreams i remember, i was in an underground bunker and it was mostly empty, there were 2 bunkers and a opening connecting both, when i reached out to my mother, i touched her upper forbidden parts and ejaculated in sleep and woke up disgusted by it. In the second dream,we went down in a basement (it seemed like basement of a hotel it was very fancy with a big aquarium in it as well), sat for a while and then got up and as we were waiting for the lift as it was coming down there was a shaking and i held my mom for safety (from behind i wrapped my arms around her) and as soon as my genitals touch her private part, i ejaculated in my sleep and woke up.. .
I’m a college student and the youngest in my family, while my brother and sister are the bread earners of the family. my mom and my dad are in old age and when i get back from college i do my best to look after them both. From feeding food to my mom to pressing her legs i do my best and I don’t have any sexual attraction towards her. Im really confused of what does these dreams mean.
JazakAllah khair.
