I have that happen to me (called depersonalization) when stress gets bad & I'm not sleeping good.

It never happened to me before I went through the trauma with my Mother when she was dying.....then it hit really hard.....after that, it seems like it hits when I am more stressed.

It was interesting in my DBT group on Monday, the leader explained that depersonalization & dissociation is part of the Pushing Away distress tolerance crises survival strategies. Not something to be used as a first technique. It's not something that I have ever been able to do on demand....it just happens with me & it's a very scary feeling for me....but it's been happening more to me lately & I have seen my stress lever is much higher than it has been for quite awhile & my sleep is horrible other than when I crashed for almost 24 hours the other day my DBT group.....was completely exhausted....fell asleep & when I woke up had no idea what day or time it was....another really strange feeling.

When it first happened to me, it really scared me, but the pdoc I had at the time was the one that told me what was happening & knowing what was going on helped some......but still didn't make it really feel any better.
