I am a victim of a wildfire that claimed my home. I live in an area where there are fireplaces/controlled burns going and it is often foggy, so I've been able to come over the sight and smell of smoke, but when I have anxiety I see smoke that isn't there. It's like a hallucination...it takes a few seconds for my eyes to figure out it's not really there and it's gone...is this normal for PTSD?
