My experience is similar. I don't think I have ever experienced derealization or it's companion state depersonalization in nature.
I think maybe my earliest experience of this was when I was a child and I became convinced that all the adults in my life, parents, teachers, babysitters... were part of a conspiracy wherein I was the subject of an experiment. They were not what they appeared to be and they were testing and observing me. I couldn't have been older than 7 at the time.
From the op wiki article:
Derealization is a subjective experience of unreality of the outside world, while depersonalization is unreality in one's sense of self. Although most authors currently regard derealization (surroundings) and depersonalization (self) as independent constructs, many do not want to separate derealization from depersonalization.[2] The main reason for this is nosological, because these symptoms often co-occur, but there is another, more philosophical reason: the idea that the phenomenological experience of self, others, and world is one continuous whole. Thus, feelings of unreality may blend in and the person may puzzle over deciding whether it is the self or the world that feels unreal to them.
I think I fall into the latter camp that does not want to separate derealization and depersonalization. I think I experience both at the same time, although if I reflect on myself it tends to banish the effect and reroot me in consensus reality.
I posted the following poem in the Poetry Slam thread awhile back:
THE MAP OF THE HANDWhat territory is this?
What rivers, what boundaries?
Whose bones beneath the ancient mounds?
Life, head, heart, fate--
the lines that hold us up,
that cradle us in the deep,
rocking wind of our lives.
I stare down at my own hand
like a man awake in a dream,
flying above the earth.

wikipedia wrote:People suffering from derealization have described feeling as if the world external to them were something in a TV show or movie, or as if they were viewing it through a TV screen. This, and other similar feelings attendant to derealization, can cause a sensation of alienation and distance between the person suffering from derealization and others around them.
Interesting. Have we come so far so fast from our origins that derealization is just a natural byproduct of modernity? Is the tv screen analogy just a handy way of describing the experience or is it possibly cause as well? I get a similar experience to derealization when I exit a theater. I almost always get a similar experience, at least momentarily, when I wake up in a strange room.
Also from the op Wiki article:
Cannabis,[7] psychedelics, dissociatives, antidepressants, caffeine, nitrous oxide, and nicotine can all produce feelings resembling derealization, particularly when taken in excess.
Complicates my thinking on the subject, ahem.
