My suggestion is that you not only cleanse your apartment of anything that happens to be lingering around, you bless it and claim it as your space. It's not rocket science. As it's *your* home you certainly have the authority to do this yourself (whatever your religious belief).
First Clean the place. Literally. Clean all the surfaces you can, mop the floors, clean all the rooms, scrub the toilet, vacuuume, etc. (by doing this you are not only physically cleaning, you're using the power of your subconscious).
I'm fond of "write your own" ceremonies (they don't have to be particularly formal, mine never are), using stuff that makes sense to *you*. You can either do the ceremony by yourself, have your daughter help (good as she was afraid), or invite like-minded friends over and turn it into a party (always fun if they won't think you're strange).
THe basic structure is this:
- get rid of unwanted stuff (dirt, energies, 'spirits' if you believe in that sort of thing)
- cleanse the space (physically, spiritually, emotionally)
- claim the space as your own (as simple as an announcement that 'this is my home, I claim it as my own, I say what goes here!')
Suggestions:
banishing: open all the doors and windows you can to allow things to 'escape', move counterclockwise throughout the home, sweeping (New broom) the old, unwanted stuff away as you go, 'sweep' from inside to out, all the doors and windows; also good for banishing is noise (kids like this) noisemakers, banging on pots and pans, etc...pretend you're chasing or driving the old, negative, unwanted stuff out
For the rest of the ceremony, actions move clockwise, the direction of bringing in and welcoming
cleansing: candles, incense (the type your church uses if you're Christian and they have one), holy water if you're Catholic, Sage and Sweetgrass (burn the actual leaves [ps-not culinary sage, you can buy bundles of sage to burn]); I personally cleanse with
fire and air: incense or sage - 'smudge' the rooms, esp the doors and windows
earth and water: water mixed with salt (earth) - sprinkle it on stuff, esp the doors and windows
Claiming: mark your territory as you see fit. I have a friend that loves special stones and uses them to mark the boundaries of her space, be creative. I don't recommend doing it the way dogs do, though...
