You're just being finicky. You know exactly the sense In which I was using flashback you little cock goblin. Of course you can have a PTSD "flashback" but you can get those from being at war and in a car accident too so it's not specific to acid. You and I both know I was referring to the traditional view of an acid flash back.
People claiming to have a "flashback" are referring to an actual visual hallucination or body high that is either neutral, good, or bad, but has been shown to be due to natural effects of different things on the body which was most commonly connected to slight dehydration.
