For me, flashbacks have a huge emotional component as well as the extreme adrenaline rushes. My body contorts, terror rules, and 'something' is overwhelming me to the point I"m just not able to cope with anything and calming down is incredably difficult, if seemingly impossible and takes a long time.
I don't have 'pictures' that come with them. I know I'm not in the present, but I don't know really what's happening to me.
My intrusive thoughts are his 'eyes', the screaming and hatred in his body mannerisms, the fists flying at me. These things ruminant in my mind, especially when I lie down to sleep.
Flashbacks are like my body trying to get away, with no hope and the 'for-certain' terror that I'm going to die.
