You say your house is dark and creepy.
Try plugging a few night lights in the darker rooms.
Do you like angels or stuffed animals or is here something else that makes
you feel safe and happy. Or is there a fragrance that relaxes you.
Put those things in your bedroom and around your house

Does your dog sleep in the room with you.
Your dog is your protector he is not going to let anyone in the house
let alone next to your bed without barking his head off.
Go to bed with positive thoughts that your dog is your superhero
he will keep you safe while you sleep.

If its always the same dream.
While your awake think of what you would do, go through
the whole thing in your head. EMPOWER YOURSELF.
then when the dream comes you have your own ending
Good Luck
