Things like that that I've had:
*A strong sense of walking about 3' behind myself (like I was not in my body, but an invisible one walking behind me).
*A very strange feeling of not knowing for sure where I actually was (the places being 3,000 miles apart no less(!)). If I'd been asked, I probably would have answered correctly...but wouldn't have actually believed it. That one's hard to describe, but it was like my head and body were 3,000 miles apart. That was occurring during a 2 month long horrid mixed episode. I was a psychological hot mess (with no psych at the time).
*A sense of being invisible. That's common figuratively of course, but I veered into literal territory with it. Its start preceded the onset of my BP (at 20) by a number of years.
*That my face wasn't my face, but a skull with eyes set way back in the sockets (ewww, lol). I'm pretty sure I didn't see it in a mirror, but was otherwise convinced that that's what it was and what others saw. Which horrified me. (It didn't really occur to me that if that were so, there would have been freaked out reactions (ya think!?). It was in the midst of a long severe depression.

Those are some that come to mind. Sorry so long. You're not alone.
