i remember seeing some schemas floating around on here like "if you close your eyes you wake up." "if you don't stabilize the dream won't last long" "don't ever say will in your mantras"
here's a positive schema, you can reject schemas if you so choose.
this may or may not work, but if you fully believe something isn't true, then in your dreams it won't be. you should be able to make that work for you.
