I do zone out a lot, but not to where I'm thinking of nothing. Usually I'm imagining things happening. Then promptly confusing myself as to what happened. Another problem I have frequently is I hear things wrong. I can't understand what people are saying to me sometimes, like the words are foreign. I hear what they say but my brain isn't translating it. So I try to concentrate and get them to repeat it in a way that the words they said are completely separated on their own. By this point though, they think I'm retarded.
