I'm sure there must be a technical name for this so that I could google, but I have a hard time describing. Maybe somebody can tell me the name?

This seems to be a form of depression, but it doesn't feel bad. Instead I feel like I'm not quite here. Like I'm floating or half asleep, but I got a good night's sleep last night and I'm not tired or sleepy. I don't feel safe driving a car, and it feels like my arms are 10 feet long as I type. If I didn't have work to do, I could enjoy this feeling. I might go meditate, because it feels like I'm already in a trance. But I have work to do, and I keep getting distracted ... thinking about nothing at all. I just notice a color or a sound and become engrossed with it. Then I pull myself back and I feel momentarily confused as if I had just nodded off briefly.

What is that called? Sometimes I wonder if it is the negative symptoms of psychosis? It doesn't feel bad at all, but I know I am struggling with depression right now too.
