I get issues with depersonalization/derealization. I'll feel like I'm in a dream and can't wake up, on the outside looking in, or like I'm floating above my body. I get these when I'm having relatively bad anxiety or mood issues.

I get the highway hyponosis stuff, and I've experienced a disconnect while running too. I don't consider these quite the same thing, as these I get when I'm not having issues with mood and anxiety.
