Maladaptive daydreaming is a fucking curse. It hits you when you least expect it. When I was in school, even during quite important tests, I found myself asking how much time had passed since the moment before the "daydream" started. It fucking horrible because all the people you know can manage to do something even if they find it boring, but you? Not you, whenever you start doing something you find boring you get shot into some mystical journey through space and time never managing to do your job. When you have to write something the text will have all sorts of illogical connections because the daydream will interrupt your flow of consciousness. Whenever you get back on earth after having even "been" in a niec place (your dream house for example) you get depressed because the beautiful "dream" you had doesn't match reality (a bit like when you were a little kid dreaming that bike you really wanted and BOOM you're awake, no bike, all the fucking time).
