I am told eating cheese before you go to bed makes you have bad dreams.!!!
Take heavy doses of B complex. Can't guarantee nightmare, but you'll increase dream recall.
Cheese have been proven to enduce weird dreams if eaten before bed
Eat a lot just before bed.
Don't know why you would actually want to have one, but I know when I have to pee really bad I have some terrible nightmares.
You want nightmares? I get them almost every night and I want to have normal dreams again:/
Horror movies don't give me nightmares, mine are all to do with everyday things. Not sure how to make them happen though.
eat chocolate before bed
then you must be fearless
Those are usually all I have.
