Thank you all so much for responding to my question. I don't know as yet whether I have alters or not. But your answers made a lot of sense and gave me some direction and a way to look back on my experiences and try to remember what was going on with me at those times.
The dissociating part I understand. I fade away. Things look foggy or unreal. The ground beneath me or objects around me seem to move, sometimes like a flowing stream. I lose time. I can not speak or hear when someone speaks to me. Sometimes I walk on air, not being able to feel the ground beneath my feet. I feel fear, like a wall or looking glass is between myself and the real world. Sometimes I am unable to see people I know, or find them even if they are in the same room with me.
I have learned in reading that sounds can be flashback triggers. Sometimes I hear the sound of static in my head like it used to be with old AM radio stations. It is so loud sometimes it drives me crazy. Sometimes I have heard muffled sounds like talking, but I can not make sense of it all. Sorry for rambling on so, just picking up pieces of a very confusing puzzle. 1Girl
