Bold part is the same for me. I've just always had a tendency to lose myself in my imagination, as far back as I can remember; it just seems to be part of who I am.
Regarding the moving around, THAT is something I figured only I did until reading this thread and some other sources...I can't engage in actively roleplaying/pretending/"dancing" my characters anymore
so I tend to listen to music I like on headphones while walking around doing my nightly/bedtime routine, only in my head, instead of closing the blinds and making my bed etc., I'm living through a movie soundtrack of one of my stories. ;_;
When I had more time on my hands, I'd go outside and pace around and around the house and property while listening to music, for the same reason, and I'd really like time to do that more often...to me it's a bit of a relief to know I'm not the only one who does such things!
It's actually what makes me afraid, it's like I have a hidden trauma I don't even remember... lol
So true, I've been doing this since as far as I can remember, but the attachment, pacing, and making gestures and facial expression, it started to show when I was 15. I don't actually making expression like you could caught me making funny faces in the room, alone, it's just sometimes when the fantasy is so intense, you know it can affect your expression and you know you have to refrain yourself.
I don't fantasize about myself though, but a different person... and OH YES, PACING, I always say I love to walk around my house when I'm excited but apparently it's this. lol, I don't know but it's just so funny everything makes sense now. That's just so true, when I do it it's because my mind is actively working, I get excited and giddy so I need to take a walk lol.
And the part I like is when you're deeply engaged, you're pacing, then you stub your toe and suddenly you're brought to reality and it makes you feel like a fool.. such a party pooper
