PTSD doesn't work like that, PTSD makes you hallucinate. Seeing a black man could make you hallucinate thugs running towards you, or you could get a panic attack so bad that you throw up/faint/get a migraine. It could re-trigger night terrors ect. Ect. PTSD is tough. I've got a lesser form, and I get a lot of audio hallucinations where I think ppl are yelling in the room over about me. It's not something you can't rationally overcome. I'm on venlafaxine. It lessens my anxiety to the point where the hallucinations are ppl calling my name. It's very nice. I recommend.
