I found the word in YouTube.

Hey everyone, my name is Jess AKA SpectraNyte, and I've been doing this MD thing pretty much ever since I can remember. (I believe I was about 4 or 5 when it started, I'm 35 now...) I'm one of those people that thought I was the only one who did this, and had no idea there was a name for it. It was just a couple of months ago that I learned what this thing is..that I do.  I was reading through the comments of a video on YouTube on Aphantasia. One person who commented said they have 'the opposite of Aphantasia, called Maladaptive Daydreaming'. They went on to describe what their MD experience is like, all I could think of what 'Wait, what?! There's a name for this thing I do....and I'm not the only one???' 

Sorry for my rambling introduction, there is more I'd like to share, but it's late where I'm at (a little after 1 am) and as tired as I am, I've got to get that DD itch out before I go to sleep...as long as the boyfriend is already asleep. No, he doesn't really know I do this...

So, yeah, hello fellow MD'ers!
