I have done this!!! Had a gander through RightMove looking for a nice big house (that I could never afford unless I won the lottery,) in North Staffordshire, or Shropshire, or Herefordshire, or Cheshire.
Preferably with around 10 acres of land, and only a short distance from a train station, and a motorway for easy transport links. DD will move too and stay in a cottage on the land with her boyfriend and their kids (when they have them.)
Usually about £900,000 to £1.5 mil for what I want! 
I would like to live in West Wales/North Wales, but sadly, as much as I love it, the transport links are a bit poor, and there's not much there, regarding leisure facilities, and employment opportunities etc...
Is all this this called maladaptive daydreaming or something?
I know this can be quite severe, and affect peoples everyday lives, but it can be mild too, and harmless.
