My panic attacks include me screaming, when I have what I refer to as an "all-out" panic attack. That's when it peaks, isn't just severe anxiety or a lesser panic attack, but is like the equivalent of an orgasm, only instead of the peak of pleasure, it's the peak of fear. I think all emotions have peaks (like rage can be the peak of anger).

I don't want to scream, but I can't help it. I start screaming, begging for help. One shrink I had in the past said I could choose not to scream, but that only p***ed me off, because I try everything to NOT scream, since that seems to escalate the panic, and I can't help it.

I can't truly give you words to describe what I feel, but I can tell you three movies in which I've seen scenes that are similar to what a panic attack is like for me, at least in part. In Twilight Zone: The Movie, the scene where John Lithgow plays a man with panic attacks and flying phobia totally freaks out, that's a good depiction of the one of the sensations I feel. Saw and Saw 2's terrifying panic moments are also good.

I really hate the way Hollywood usually portrays anxiety attacks and panic attacks, though. They're often wrong. I remember one where a woman had hallucinations, and they called that a panic attack. That's not what a panic attack is! I suppose a panic attack can include hallucinations, but it's not what a panic attack is.
