K hole?

Pretty sure I experienced a k hole and I'm wondering if that's a good thing? Was it helpful to my healing or detrimental by experiencing this? I'm starting to have flashbacks of my last experience and the flashbacks are of memories of my past but memories of what I experienced in the K hole. I'm scared this is a sure sign that I've been traumatized more. I'm doing it for PTSD and I'm doing I IM injections. I don't think something helpful would cause flashbacks but idk .
