Yeah that might be it. What I mean is that I don't feel like I'm actually here - everything feels flat and dream like, rather than in the moment planted in a physical space. I thought this was normal though, aren't most people constantly in that state due to worry about the future or obsessing over the past? And that's the point of meditation, I think... To bring yourself into the here and now. I do some regular meditation and get glimpses of feeling more awake and present, but nothing persistent so far.
I have depersonalisation disorder. I got it from drug use. I know that at leadst for me it's not normal. I still remember what it was like before and how different everything is now. I feel the same stuff you are describing.
