...and before today I didn't even know that this feeling had a name so I feel pretty good now, in a detached and dreamlike way obviously.
I have had four episodes of anxiety over the past 7 years (fourth one right now) and they have all had, as their main symptom, a feeling of not existing in the physical world. My own house seems unfamiliar to me. It's made even weirder now because I have just started a new job and so feel doubly detached. Also my dreams get very weird when I have anxiety and DP/DR - I tend to have hyper realistic dreams which kind of merge into my waking hours. Also, I can sleep for hours and still feel tired. Plus, a lot of my dreams become, how shall I say it, sexy. Not sure if that is typical!
My other DP/DR and anxiety attacks have all gone almost as quickly as they arrive so I am hoping that this one will, too. Either way, I'm just glad to find out that this has a name and is a recognised thing!
