ummm well this is what it was like for me/worked for me...
You can do a couple of things I think, one check if there are laylines in your room, maybe there is one running right across your bed...that was the case for me and I wasn't able to sleep at all. So once you figure out where the laylines are then you can move your room around accordingly.
You can do this with a pendulum or dowsing rods etc, just take something that is dangling from a piece of string for that matter and let it swing freely from left to right, youre not swinging it though, have the intention that when it hits a layline then it will swing in the direction of the layline. Start from one side of the room to the other and work your way over the whole room.
Also do a quick feng sui thing that I once read and that was to imagine that your room was filled with water, where would the water pool? Hence those are the areas were energy may pool and just by putting a crystal in those areas or getting more sunlight into those areas will help.
You can also maybe get a crystal, maybe even a protective crystal and put it on the t.v so that it will sort out any disturbances the tv might create.
Just a question: Do you watch scary things on tv?
Its just that my exflatmate was into that and it really didn't generate a wonderful feeling in the flat.
You can also smudge the place
You can also say in a really firm voice. "Get out and never come back again" - while visualising a door closing kinda thing.
I dedicate my room to the highest of all light and have a strong intention that my room is my sanctuary and that its like a cocoon of safety and nourishment. I also will say things like only things of the highest of all light are allowed. Anything else not of the highest order, get out.
It seems to have worked but sometimes there will just be those evenings when you feel things moving around and the best thing is to just stop yourself from thinking too negatively, don't assume the worst.
Call on the Archangels, esp Michael and Gabriel, they are great for this kind of thing, also just ask your Guardian Angel. I think they get so bored cause not too many asks for their help anymore! heehee So I ask all the bored Angels to come and help to
Well I hope that helps a bit - gets those ideas running on what might be best for ya.
Interested to see what wimery has up the sleeve too
