Here's my responses to it.
1. Find yourself staring at one spot, not thinking anything:
Yes, frequently
2. feel completely numb
Emotionally sometimes, but not physically. Like I'm feeling depressed, or upset, but don't actually feel the emotion. Or know I should be having a strong emotional response, but don't feel anything. Like, after 9/11 I was more bothered that I wasn't upset than I was upset that there was a tragedy.
3 feel like your not really in your body/watching yourself like a movie
No, I don't think I do this.
4 Dizzy or lightheaded
During panic attacks, yeah, but I'm hyperventilating. Also when I stand up, becuase I'm tall.
5 lose the plot of a show or conversation you were focused on:
Multiple times per conversation, almost any conversation.
6 feel as if you're not quite real, like you're in a dream:
Since I was a kid, assumed I was just weird
7 feel like you're floating
No
8 suddenly feel like you're not a part of the world
Sort of, more like I shouldn't be, and that it makes no sense that I am
9 feel detached or far away from other people
Separated by an impenetrable barrier, but not so much that they're mechanical
10 are startled when someone/something gets your attention
To an extreme degree, all the time, yeah,
11: completely forget what you were thinking just a moment ago
This isn't normal? I do this frequently
12 suddenly cover your face or react as if you're abut to be hurt for no reason
I'll feel like I'm in danger, and want to curl up into a ball, does that count?
13 can't remember important information about yourself
No, I don't think so. I do have a very poor autobiographical memory, though.
14. find yourself rocking back and forth:
Frequently, especially when anxious. Isn't this just an anxiety symptom, though?
15. become very focused on a small or trivial object or event:
Yeah, enough so that I'll be late to work trying to resolve it when I could safely ignore it.
16 find that voices, sounds, or writing seem far away/have trouble understanding them
No
17 feel as if you just experienced a flashback (perhaps rapidly) but you can't remember anything about it:
I don't think I'm capable of traditional flashbacks as I have no visual imagery ever while awake, so if this happened, I wouldn't have anything to compare it to, that would make me think "that felt like I had a flashback." I might have emotional flashbacks, but I'm not sure what it would mean to have one and not remember anything about it, but feel like I had one.
18 Percieve your body as foreign or not belonging to you:
Other than gender dysphoria, not really.
I think most of those are explained by other conditions, though. Is this a bad list?
