I have been an extreme day dreamer all of my life, creating elaborate fantasy worlds in my head.   I have a similar story to many I have read about on this forum so far and I have  most of the symptoms listed for maladaptive day dreaming.  I am fifty years old, married with grown children and a professional educator.  

In the course of my life I have been able to actually apply my day dreaming to creative pursuits.  My day dreaming became the source for artistic expression and writing.  I have an art gallery based on my day dream imaginary world at http://mistgod.deviantart.com/

I have a "day dream star" living character (a character who has become very real over time and seemingly semi-autonomous).  Her name is Melian.  I actually "channel her" (portray with a form of method acting)  online.  Here is her deviantart page and profile: http://melianofmist.deviantart.com/

Anyway.  That's it in brief.  If you have any questions or comments I would be happy to go into more detail.
