What advice/suggestions do you have for someone who sees ghosts/dead people regularly (and is disturbed by it)?
I have seen the dead and ghosts and night visitors (three different populations; definitions (mine) to follow) all my life. In my case, they average a dozen or so a year - sometimes more, sometimes less. It takes some getting used to. Especially if the person still thinks they're alive.
Knowledge
is power. To help you get some privacy and peace and quiet, rather than for protection, it's important to understand what you are seeing and how to interact with them. While there are some malign forces out there - that's really just about as rare as real angelic visitations (which convert the person on the spot, no question).
As to the populations:
Dead People: people that you know or who know you and are in fact dead - usually within minutes of death out to about 3-5 years post mortem.
Ghosts: people you don't know, but have some sense of personality, haunting buildings day and night, sometimes (rarely) a real dead person, more often their shadow or the building's memory of them.
Night
Visitors: people you don't know, and tend towards stereotypes, or are hard to see clearly - moving in a blurry way, the 'cobweb' people. These are Fairies (a la the Gray Havens of Tolkien fame) and other subtle-world people.
Dead People: Often they don't know they're dead, in which case just greet
them and wish them well on their journey (it's not your job to handle the
transition - it should have happened at the time of death, and is now between
that soul and its guardians - unless there's a powerful (and brave, loving
shaman handy). I take the attitude of greeting someone from my past that
I have fond but mild feelings for - a college buddy, etc. Sometimes they
do know they're dead and are here to give or receive a message - if they're
not distraught then you can be open to them - there will be no verbal or
mental communication in terms of thoughts or speaking - just a communication
of feelings or intentions (this can include the transmission of a request
- sell my old house, bury me in the woods,) when such communication occurs,
usually you don't know it until after the vision has gone, and as a sort
of after-glow you now know what to do. Do it, if possible, and take your
time - they're dead! If they're distraught, imagine holding them in an embrace
or taking their hand (unless they're somebody that disturbs you) and guiding
them to the nearest holy place - preferably one that they'll recognize, and "dropping them off" there. This may take a few trips. If you're disturbed by them - a nasty uncle, whatever, -- then call the angel-dogs: sort of seeing-eye dogs for the spiritually blind - they look like what most people call angels (real angels are slightly larger than the moon) and imagine handing the dead person over to their care - willy nilly.
Ghosts: If of a dead person, treat as above. If it's part of the building & you like
it, fine, if not, either move or clean the building. In most cases, don't contact
or talk to them - they're like cats: if you feed them with direct attention
once, you'll never get rid of them. Better to ignore, or treat like cats -
don't let them crowd you. Clean by smudging,
camphor burning (my favorite)
and washing all surfaces with cold water & cider vinegar (PB's favorite).
Leave a psychic deodorant on all the time: a white candle burning - preferably
either simple or with a traditional religous image. Don't leave candle unattended
- poltergeists can tip it over - as can the wind. Do sleep with the candle
on - use the little ones or the eight hour ones. If you put them on a non-flammable
surface (like in a sandbox) below the bed's height, then all you see at night
is a circle of light on the ceiling - so that will keep the bedroom clear at
night. I basically have a white candle burning at all times in whatever room
I'm in. I add incense & holy music (not at night, usually). This is usually
something that occurs only in old buildings.
Night Visitors: (I discussed all this with Anthony in my twenties and have incorporated his suggestions along with my own.) Here Anthony bluntly said: they're living in a time/space/dimension that fades in and out of our own; leave them alone. Generally that's my advice. Don't worry about them. There's something weird about them because they're not human - they're part of the 'old races' - faeries, the 'shii' of Ireland, etc. At this point fewer of them believe in 'humans' than we do of them, in any substantive sense. Occasionally there's something to be exchanged here - but I doubt it. Like walking into the wrong locker room, just turn around and go back out. Again the white-light and spiritual icons will create a quieter room. Only keep those icons and statues around that you have a relationship to and don't let them fade into the woodwork. I add and subtract various pictures, stones, and statues (I increase with the waxing moon and decrease with the waning, until I'm down to a very few on the new moon). The point is to fill the room with your own consciousness. This is particularly important in the bedroom, since we're variously unconscious here - sleep, sex, etc. It's good to add the other half as well - prayer, meditation, a conscious environment.
