I sometimes get that feeling of "floating" slightly above myself, like my "self" was above the back of my head. It's not like I can see myself from the outside or anything, I still see what my eyes see and everything, though it gets a little unfocused, like when spacing out. This happens only some times when I'm up and sitting, and only once when I was walking. It made me feel like I was walking down some stairs and "missed a step" every once in a while, even though I was walking on flat ground. I was getting a fever at that time, so I thought it was only because of the illness at the time.
Usually, I get this feeling when in my bed, like my mind retracts from my head and beyond. Still having some connection with my head and body, but it feels like the connection is "stretched", like I'm feeling/thinking through the wrong end of a telescope/microscope and either my mind or my body feels really small and/or far far away. I can still control my body like normal, it's only the feeling of it that's "off".
I can cause this feeling on purpose sometimes. I used to do it when I was younger because it's kind of an interesting feeling. And I got that feeling now, by writing about it. I usually find myself rocking very slightly back and forth, and when I get the feeling in bed I'm usually making these rythmic motions with my leg. I don't know if the rocking or the feeling comes first, or if one is causing the other. When I was younger I thought I might have some motion induced epilepsy or something, because of the rythmic motions.
This only happens some times, and it's not really a problem for me, it might even be normal, I just thought I'd ask if this is is similar to depersonalization (cause I'm not really familiar with the term or the symptoms). Some light version or something.
