There are instances in which I will be overtaken by a very strange sort of dizzy. It is rather difficult to explain, so please bear with me.

It is as if I am looking at the world through my eyes-which, I suppose we all do. Imagine you were put into the body of a doll and now saw the world through those eyes. You move your hand, and are aware that you control its movement, but still it doesn't seem as though it is your hand.
The world looks off-not fuzzy or blurry, just off. It looks a lot like the world does when dreaming. And your hand seems far away. Like one of those first-person video-games.

It's very disorienting. I've been attempting to isolate the cause, but it seems to just happen whenever. The last time it happened was a couple nights ago right in the middle of talking with my uncle and father. I wasn't anxious or upset; I was just goofing around with family.

It has been happening for about a year or so-not frequently enough for me to go to the doctor, but enough for me to start wondering if it's normal. As a little girl, I would quite often be unable to tell whether I was awake or still dreaming and would constantly ask my cousins if I was still sleeping. It wasn't a dizziness back then, but the world still looked "off".

Is this what is called "derealization"?
