Ideas to face an evil presence:

"Hey, can you leave us alone?
If you want to scare someone, think big and scare someone more important than me.
How about scaring a world leader instead of me? Sounds good?
I am too busy to be scared. So please, scare someone else.
The world is too big, so you can scare someone else."

Fear of presence will only feed that presence.
Don't feed the spiritual troll.

This house is yours, but you need the conviction of that.
You must imagine a force field around the house.
All negative forces will be bounced off the field.
Internally you must imagine you have the power to clean your house of trespassing evil spirits.
Only good spirits with good vibrations are allowed.

Be in spiritual command of your house, like a sargent would be in command of his squad.
