Yes, and it can actually come out years later in someone too if something triggers it.

You probably had a lot of things you experienced that you never processed. Are you seeing a therapist right now? A good trauma therapist can be very helpful, the therapist I had seen explained to me that part of my healing with him was because I needed a witness which is what he did for me.

I am sorry you experienced an unsafe childhood, you deserve to heal from that.
