I am sure that you have been told that there are many types of Ghosts or Spirits roaming the earth and other dimensions. Rightly or wrongly - these are often put under the general heading of 'Entities'.
Orbs, which most people say are no more than mere dust particles on a camera lens or floating in the air. I have to say that most of the Orbs that I have captured, I know, are true energy form Orbs. I cannot speak for others' recordings of Orbs. Granted I have captured many dust particles, sometimes on purpose. When I first started really looking into Ghost Photography I wanted to know what the dust looked like and what the Orbs looked like - and if I would be able to see differences.
Orbs vary in size from very small to very large and tend to be beautiful circles of rainbow type colors, with rings or spirals in the center or immensely bright white or gold light.
A Vortex is a type of mature Orb. I guess one could call it a more mature Orb. Orbs can manifest into a Vortex and this type of Spirit looks like circle orbs connected to each other.
It is difficult, sometimes, to tell the true Vortex from something that gives such an appearance - I have seen a few photos with flash highlighted hair in them but a true Vortex has a unique look to it and it does not look anything like flash highlighted hair. I have also seen camera straps in photos that the flash made a bit transparent and this too does not look like a true Vortex form.
Ghosts and Spirits
There are Ghosts of the dead or Spirits (souls that have passed on from life) that can actually manifest or materialise themselves in order for living beings (sometimes, without psychic sight) to see them. These types of manifestations or materialisations can look like humans or animals depending on what type of being is trying to come through. However, not in all manifestations does the full being come through. It can look like mist or a cloud in a human or animal outlined form or a partial manifestation of limb a head or some other portion of the body. Are full manifestations rare? Some people seem to think so!
Residual Ghosts or Hauntings
There are the Residual Ghost or Hauntings where the being continues its day to day existence without any awareness at all. These ghosts are not aware of you, the environment around them or even that they exist at all. In my opinion these are true Ghosts.
Intelligent Ghosts or Hauntings
There are the Intelligent Hauntings where the ghosts or spirits can - and more than likely - will try to interact with you. The ghost is seemingly aware of its surroundings and of itself.
However do you know what is happening in an Intelligent Haunt? Have you ever heard your name being called out when no physical being is around? Have you felt something brush up against you and no one was there? Have you maybe heard weird broken sentences from behind you? You have!
Now have you ever interacted with the being? No? If not, why not? If by interacting, you could prove to the world that Intelligent Haunts do exist - would you then start interacting back?
Poltergeist is German for 'noisy ghost'. While it is thought that their 'noisy' activity does not eminate from the Spiritual world itself, many do believe that a Poltergeist is from the paranormal realms.
An enormous amount of people believe that a Poltergeist is no more then a type of PK activated 'ghost'. I see them as more than simply this, so I tend to disagree, feeling that their energy comes from other sources. I have met others who view it my way too.
Then there are the rare but very much heard of Demonic Haunts. These are very negative presences. There can be a foul smell like sulfur or rotten eggs - making some people ill and drained of most of their physical energies.
I have read about and watched shows where the demonic presence was not of a once living being but developed in some other way. To say there are no demonic presences would be to blind yourself of the reality of the spiritual world.
I try not to ever be in such a negative place, for example, a place of a heinous crime or where others have performed some sort of rituals to summon Satan or demons. Demonic presences appear to have sometimes altered the mind or thought process of its host and or made its host act completely differently to their usual behavior. This comes from oppression and possession. Oppression is to control from outside of the body and Possession is to control from the inside of the body.
That's all I want to know about the negative side of the spiritual world. I do not like to delve into it because I believe opening the mind to that side also opens a portal for such activity and I never want to go there ever again. I do add, though, that this is just my belief and others may view it differently.
There are Messengers that some put in the same category as Ghosts - I like to think of a Messenger as an Extra Celestial Beings as well as Ghosts. More often than not a Messenger is of a passed loved one - either a friend or a family member.
The Messenger is just as the name implies. It comes to those in need of comfort - usually just after its physical passing - to tell the loved ones that they are safe and happy on the other side. Some Messengers have told their loved ones that they went to Heaven and saw another relative and they too are fine.
Now, I do believe there are Messengers - Extra Celestial Beings - these are Angels or Guides or Guardians and they provide a warning, a message or a sense of comfort. I believe that Extra Celestial Beings also send physical people to us in time of need or to help protect us in some way. I have never feared a Messenger.
There are many more types of Ghosts, Spirits and Hauntings and if you are seriously wanting to know them all - or just a few - I recommend looking through this website's many areas, or the forum - you are bound to find something interesting and informative.
