I can't feel at ease if I don't finish my daydream till the end.

[NovBaby]

If I'm daydreaming most the time I need to finish the daydream. Not all the time but if I'm really really focused. If something comes along in the real world, in the middle of my daydream I get mad and pissy. My daydream feels incomplete and I can't "rest" until I finish it... My daydream is always the same, sometimes I switch little things around, I already know what's going to happen, but I need to live it in my head until the very end  for it to feel real. it's an obsessive feeling. Anyone else?
