I had similar experiences long ago I think. I was burned too back then because of bad treatment from others. Inside I felt like...Lets say "empty, rusty and large oil barrel". Felt like if someone will knock my chest -very loud empty sound will be heard. Back then I felt disconnected from everything and everyone. Could not laugh, cry, fear or become angry. Just completely passive feeling to everything, just existed. But one thing I remember, one feeling...Or was it thought? I felt like I don't belong anywhere.
In my eyes and mind I frequently saw myself from the side, walking, carrying my legs. I could not feel myself from inside, but somehow saw my condition from the side. Every step felt like I am walking in a swamp, now if I think. My body was walking into the shop, but my mind were somewhere else. Someone was talking to me -but I did not understood a thing, also could not remember anything that was said to me. But for some reason I remember and understood well, what people about 5 meters from me were talking. I was close to them, but absent with the person I stood in my physical form. Those was just short moments. Lasted for about 5 minutes, then I felt my body again, but it repeated frequently. More long periods of this was when I was laying or sitting somewhere on bench. It was like I was watching a live stream about my life. Its been many years since this happened to me last time I think. Or maybe it was time when I paid attention at it. I was not afraid of this feeling, I just couldn't scare back then or feel much of anything. But is this similar to what you experienced?
And actuallly I havent thought about it until now. I think I don't want to give away any thoughts yet. But I am interested in this topic now. O_O
