I always used to be an insomniac, and as such learned to cope by just daydreaming so heavily and so vividly (Strong congnitive imagination. Have conversations in my head with someone next to me a lot etc) and I can get a lot of energy from there. Also I love sleep and get depression so even now that I'm not an insomniac I still zone straight back into sleep after waking up and turning over and may do so for about a week if left to it, and daydreaming about things that are better than my day ahead often seems more desirable. Not complimenting this especially well is my ADHD, which means both that I'm far more likely to zone out at inappropriate times as I get bored more easily, and go off tangent from things that someone said and start thinking about or having a mental conversation about that instead until I'm lost. Of course another symptom of ADHD is disfunctioning working memory. Sometimes you forget short term memory, but often your brain doesn't read your working memory and put it into your short term memory box in the first place and so there is no memory to remember. This can happen when you ARE paying attention to what someone says, and you cannot focus both on remembering what someone is saying, and also processing the meaning of it at the same time. It literally does go in one ear and out the other against your will sometimes. Now add that to when you are not paying attention or are in a trance of just "doing" stuff on auto-pilot, as we often do, and you're going to have to just memorise that your keys can usually be found behind your laptop, because you don't have a single memory of having ever put it there even though you seem to throw it in that absurd position every day. Maybe this will help some people?
