Have you ever felt like you were in a constant dream state

Yes. Then, I found out that most of it was due to Candida Overgrowth. The other part, I am left to assume, was from being abused as a kid as that can cause derealization/depersonalization.

I detach and space out when I am stressed, like a light trance. But actually seeing your surroundings change is not normal at all, it's never normal for things to look foggy unless you are standing in fog.

Yes, a lot when I was a kid I would be with my family and suddenly they'd look like strangers... Then I would get kind of lightheaded as so many thoughts were rushing around... And other times when I was older, it was a sort of depression I guess, that made everything seem unreal, and I kind of wished that were true, that it really was all just a dream...

Yes, and I realize I'm not the only one. Derealization is somewhat common and can happen for all kinds of reasons. It's only a problem if its bothering you or comes with other disabling symptoms. The only problem I notice with it is I am spaced off and often unaware of what's going on around me.

I've only experienced that when I was on drugs or chemically imbalanced you might check on both. I haven't had that happen to me since I've been straight.

Sounds like derealization. My psychologist said it was the bodies way of dealing with trauma. I experienced in the most right upon learning of my fathers death. It lasted for a 2-3 months on and off but slowly became less and less and issue when I started becoming more positive.

Keep in mind I'm not a professional just someone who is dealt with it. And I have my own questions about why it happens. If you don't mind, I'd just like to know if you're isolated often?

I sometimes feel im not really of this world ,and should b in a parallel universe, or an alternate reality. I think its because I get Deja-vu a lot. But I have a very good intuition. Maybe it's Deja'vu related.

Yes.
