We all have one, we all ARE one, and it's the animating personality that a body would just be in a vegetable-like state or coma [or dead] without one.
According to some beliefs, the spirit enters the body before its born to have a physical corporeal life. Again according to those beliefs, at death the spirit separates from the body and continues its own non-corporeal life.
Now you may not agree with those beliefs and it is alright, but I do believe in that myself with proof from my own communication and channelings with the spirits as well as memories from the time between physical lifetimes that I have gathered together over years of soul searching.
Therefore I will put the warning that this post is purely from my own perspective, experiences, and beliefs so if you feel you do not agree then take what you will from this and move on. :)
Earth occupies the 3-Dimensional Physical plane and the energies are slower and denser and very solid and not willing to change as much. The Spirit Worlds can overlay Earth and be hard to sense or see with physical senses (but can be perceived by the psychic senses that everyone has but most of the time those psychic senses are drowned out by the dominant and stronger physical sense input). The Spirit Worlds often lay on the Spirit Plane, a faster moving and lighter and quick changing and "higher" (or greater or increased) vibration of energies that makes up that world.
Therefore if one is a spirit or ghost they occupy this plane, with spirits ranging in all the planes but ghosts bound to the plane just above the physical earth plane.
Ghosts are essentially spirits themselves but something happened so they are restricted to Earth and not able to move on. They are a higher vibration than physical bodies so they can not usually be seen or perceived without a huge effort made on their part, and can affect some objects (hence throwing objects and other effects that can happen), but it does take a toll on them to affect that much of the very solid physical Earth objects. They go through walls due to being able to energy shift deliberately to "phase through" the walls, but not the floors or things under them unless they should choose to do so. It is more of choice what they go through and what they don't, and some can be confused and not realize they can do this and therefore just stick to normal human walking paths.
This next section will deal with Ghosts more. Other sections in the future will deal with the general Spirits.
GHOSTS:
It has been my experience that a spirit can separate from the body after death but something happened that was so traumatic in the separating that the spirit is confused and thinks sometimes it is still alive and in a physical body and lingers on the earth plane.
These become "ghosts" essentially. Some can be malevolent and angry, some withdrawn and sad, some frightened and upset, some friendly but thinks that they are still living in the house and then would become angry when they see people "invading their homes" when they are still there.
Some are genuinely afraid of the afterlife out of not knowing since that fear in life can translate to after death and keep one from moving on successfully. Some just don't want to move on and may have something tying them here, whether it be a memory, grief, old debts, vengeance, or the like. And some just don't care to leave Earth (though if they were told they could come back as a spirit guide of someone else serving an earthly lifetime, then they might be more willing to move on to the Spirit Plane with the rest of the spirits after death).
Caution must be taken with a haunted place or with a ghost since they can be as varied as the humans you meet on the streets (which is apt since they usually WERE humans in their physical lives and would realistically act in similar ways too) and the cause of their deaths as well as the reasons why they are lingering can be unknown. It is advised to leave it to a trained medium or priest/religious head in whatever religion you believe in to deal with these ghosts. Some can get very ANGRY and dangerous if they perceive you are trying to "get rid" of them by making them move on.
Accomplished mediums usually work to convince the ghosts that they do want to move on of their own free will and soothes any worries the lingering spirits might have of the crossing. Mediums also must take guards against those who simply don't care to move on and who would attack them if the medium tries to force them to move on. It takes considerable mental discipline, Willpower, and spiritual belief/faith and abilities to force a recalcitrant powerful ghost to move to the other side and withstand the attacks that may be thrown at them.
Generally it is ill-advised for anyone to just read up online and decide to "become a ghost-hunter" themselves and plunge right in over their heads with the spiritual world without even knowing the slightest thing about protections, clearing/cleansing a space, what tools are at hand to use, and how to communicate with them and respectfully talk with them, as well as how to hone one's own willpower and mental discipline in case of mental battles against aggressive spirits, and what to do when severe warning signs are appearing.
Some of those warning signs might be:
- Blood or other liquids oozing out of the walls with no definable source
- "Evil" or malevolent air in certain parts or in all of the building (trust your gut when its sensing this because it knows best, this is the air of intent to harm and kill).
- Objects not just being thrown but consistently trying to hit you or your loved ones. Some would be life-threatening if they hit, or ARE life-threatening because they hit their mark.
- "Bad Luck" hovering around you and your loved ones. Jobs being lost, cannot sell the house, people keep getting sick [sometimes fatally sick or close to it], people die, and other very undesirable things.
- Animals not wanting to go inside the building or into certain rooms, and those happen to be where the "malevolent air" is the strongest.
- Terrifying noises happening, shrieks and screams when there is no one there, malevolent whispers that is heard by more than just you and by others who visit the place.
- Strange odors, especially that of death or blood or decaying bodies where there is obviously just clean "normal" seeming rooms.
- Often have legends or a bloody past that one can find out through some dedicated searching, almost always involving a violent death or murder.
- Visible apparitions happening now and then, usually translucent like misted glass and of people hovering a bit above the ground they walk on and making no sounds. Sometimes are too vague to make anything out, or seem like distortions of the area in a human-like shape (air distortions look like distortions in hot air locations only its confined in a humanoid shape and often is not a hot day in any way and moves across normal air).
Now most ghost cannot even try to get to this level of haunting due to inability to use the force and energy required to have that much physical effect on the world. The spirits/ghosts that CAN however are the ones to be most wary of (not to say you shouldn't be wary of ghosts and spirits in general) and poltergeists are quite fond of the warning signs above. Ghosts and spirits can generally be reasoned with. A poltergeist usually CANNOT be reasoned with.
Poltergeists are tricksters in energy form, and any response to their efforts just encourages them. Even faking no response might make them angry and increase their efforts to unsettle you. The only sure-fire way is to GET OUT of the building and not return. Also make sure to see a medium or spiritual practitioner or head of whatever faith/religion you practice to make sure the spirit didn't hook onto you and just tagged along with you. If that happened then just moving would not solve anything, it would carry on its mayhem around you and make your life a living hell (pardon the pun).
Last thoughts would be that in general spirits can be helpful or harmful or anywhere in between, that ghosts are a form of spirits that are more bound to earth plane as well as can have variations too, and that poltergeist are best avoided at all costs and are usually very harmful.
Hope this all helps!
Namaste,
