For example
You're being chased by a nix hound and you can't run right.
You're in your house and it takes you 4 hours to get your front door open,only to see that there's another door behind that one.
Your greatest dreams are fulfilled and life is great,at which point you wake up and realize it was just a dream.
You're out fighting monsters and every time you swing you weapon turns into a fun-noodle.
I'd then use dreams to influence people into buying certain products secretly manufactured by House Dagoth?.
