Maladaptive Daydreaming: where wild minds come to rest
I know exactly what you are talking about. I thought i was alone here. After a day of work i feel mentally fatigued. I cannot concentrate on any task even if my life depended on it. While I'm driving home i zone out so much its scary. I'm always daydreaming about something especially when the radio is on which triggers it. I have a lot of problems doing simple math in my head as well. Like adding, subtracting, and multiplying etc. Like i can't even play black jack with people because I'm afraid I'm going to look retarded. There is something very wrong here. And the reason why you have bad short term memory is because you have a short attention span. You cannot remember if you do not pay attention. In order to remember you have to pay attention.
I've been tired and stupid recently but that had nothing to do with daydreams, the problem was my thyroid gland, I am now on medication for life, yay:( But I have definetely noticed memory problems, like I always have to go back and check if I actually locked my locker, door, etc. Just today I forgot my OPUS card (a card for using the buss/metro in Montreal) on the bus, the reason? I forgot to put it back in pocket, headdesk.
I don't know if daydreaming is the cause, but it could be a type of side effect, not every case of maladaptive daydreaming is exactly the same after all.
As for math, I went to summer school for two years in highschool, then in grade 10 and 11 (there is no grade 12 in Quebec) I started averaging in the 90's, I have no idea how.
I know this is a really old post but thought I'd add to it as it is something I have been looking into a lot recently and I have a bit of a theory as to why MD often have a sort of comedown after periods of DD.
I really struggle with concentration, tiredness, cognitive function etc and think its because of the increased levels of Theta brainwaves daydreamers have. Theta brainwaves occur most often in sleep but are also dominant in the deep meditation, creativity and daydreaming.
"If you want to be focused on any task, though, you don’t want your brain in theta. Theta is NOT the ideal state for concentrated, focused mental activity. If you have ve ever been bored out of your mind in school and you drifted off to imagination-land, you know how impossible it felt to concentrate on your work. You had to shift back to the normal waking beta state in order to be able to focus Most people have no trouble shifting from theta (daydreaming) to alpha or beta (focused) when they need to concentrate; but people with impaired attention have trouble making the shift. An inability to shift from the daydreaming to a focused state can cause problems in learning and in work situations."
I think for a lot of people that daydream its a bit like walking around on autopilot as we're increasing the brainwaves we usually have during sleep.
