I have a problem with hallucinations, I am bipolar and have chronic anxiety disorders, I often have the issue of feeling like I can feel how it is to die by some of the ways I can see myself or others dying in the moment. 

I guess the best way to describe it is that in example: I will see a picture above someone's bed while they are sitting/laying in it, I will see in my head and feel the impact of the picture falling off the wall and hitting the back of their head and the way the glass would cut and peirce their skin. Like the sharp pain of the glass going through my skin I experience it in that moment of seeing it. The coldness you get from losing too much blood. 

I just really wanted to know if anyone had an idea for a specified word for it so I could try and find a way of coping with it or at least be able to properly research it.
