Sorry to hear you had traumatic experience. Everything what happened with us it’s written in our subconscious and unintegrated emotions manifesting through our bodies.
But whatever you forgot, it’s okay. However, hidden issues might still bother you in your dreams or reality and may appear as various triggers.
Then it worths to sort it out. But obviously everything depends on the person.
As well will text more about it in the nearest future InshaAllah.
