I was having a bad stressful dream like I often do. But then I realized I was just dreaming and that I don't want to dream this shite. So then I dreamed something else.
I wish it were that simple for me. I rarely dream at all and it's always repetitive and uncontrollable. Someone will have to teach me how to change that so that I don't keep dreaming of school for example.
It's a real gift to be able to change what you're dreaming from a nightmare into something pleasant. I wish I had that ability, I have nightmares most nights and have had ever since I was a kid (and am now 65).
On the one hand my nightmares are of such ghastly horrors and grotesque and disgusting - but on the other hand they've given me some great plots to some of my most horrifying stories.
