Hm, I don't think I have during the act of writing or reading it afterwards, but yes - sometimes I think of a scene when half asleep in bed, and it makes me cry. And that's how I know it's good, and need to be written down XD
I don't write my script linearly, but there's still a lot of 'buildup' for those scenes I 'experience' because of how long I've spent with the characters over the years when developing them, their minds, their background, their relationships and their world :'D
