The astral realm is a plane of existence close to the physical plane (The normal world). It is populated by an infinite number of inorganic beings, existing in many different ways. Humans and every other organic beings in the universe are linked with their physical bodies and their astral bodies. Others only exist in the astral realm. There are beings that feed on knowledge, or other beings. There are lower energy beings with no consciousness that were created by something else and much more.
[hider=Detailed astral beings explanation] The astral dimension contains a wide variety of what could be called non-physical subtle energy life-forms; or as Carlos Castenada so aptly calls them: inorganic beings. Some of these have a positive nature (nice) and some seem have a negative nature (not so nice). The intelligence level of each type varies enormously. The vast majority of each type appear to have their own agendas, like to keep to themselves, and in general do not like being bothered or interfered with. Not counting high-level beings like demigods, angels and spirit masters, they range from friendly and helpful, to occasionally helpful, to playful, to neutral, to mischievous, to malicious, to downright nasty and evil.
Inorganic beings appear in a wide variety of illusory forms. Some of the less intelligent types seem animalistic and predatory by nature, much like the animal and insect wildlife found in the physical dimension. I call the less intelligent, animalistic and negative types simply, Astral Wildlife. Although these all appear to come from somewhere in or near the astral dimension, many of these are capable of operating in the real time zone. And some of these, unfortunately, delight in tormenting projectors, especially new ones.
You can find absolutely anything in the astral planes, given the fluid nature of its many internal environments. In a way, the astral can be likened to the ocean: there are fish, shellfish, octopus, dolphins, whales, sharks, barracuda, sea snakes, crabs, shrimp, jellyfish, turtles, seals and penguins, etc, etc. Some of the ocean wildlife is friendly, some is harmless, some are only harmful when disturbed, annoyed or hungry, some can be unintentionally harmful, and others are downright dangerous all the time. There are also many travelers, some even from far off lands, found sailing, flying or swimming thereabouts.
Although many parts of the astral planes appear to be full of life, it is fairly rare to meet up with interested beings whilst traveling there, but it does happen occasionally. Just about every astral plane and realm has some kind of local inhabitants. These life forms often live in specific areas or realms, and often seem quite unaware there is any other reality or dimensional level than their own. They are often amazed when they meet an astral traveler. Other types you'll meet seem to be well aware of other dimensions, but most seem to have little patience with projectors and tend to ignore them.
In a way, approaching astral beings you do not know is very much like approaching strangers in the physical dimension. Most strangers ignore other people, even when politely asked directions or questions. Strangers will, at best, give cursory answers as they hurry away while actively trying to ignore you. Astral beings, like most strangers, don't seem to enjoy getting involved with the affairs of strangers, usually having much more important things to do with their time.
While projecting, you'll also occasionally meet up with other projectors like yourself, but most of these will not even be aware they are projecting. It seems that the awareness and memories projectors have of their physical existence, of who and what they are, varies greatly. Many seem as if they are sleepwalking or dreaming, or are just going along with the flow of life and events in an astral realm, as if they were a part of it and actually lived there. They are often quite surprised when it is pointed out to them that they can fly, etc.
I suspect this variability in awareness and memory is caused by many factors, such as: energetic development and activity, the amount of energy flowing into the projected double from its physical/etheric body, and whether or not a projector has made a conscious exit or not and has retained awareness afterwards. The conscious exit out-of-body seems to cause a much greater flow of energy into the projected double than is usually available to sleep projectors. It is also possible that the unbroken continuance of awareness provided by a conscious exit projection removes much of the dreamlike qualities associated with existing in other dimensions.
The most important thing to realize about any beings, intelligent or otherwise, you might come across in the astral is that they are not all dream beings or creations of your own subconscious mind. They usually have their own life, meaning and purpose; whatever that might be. They are, in most cases, not mere decorations to be toyed with or used by any passing astral traveler. Most astral beings do not seem to appreciate being questioned and annoyed, by what may seem like to them to be a constant stream of lost and meddlesome astral travelers.
For all the above, some astral beings will converse with and even actively help and encourage astral travelers, especially if projectors are courteous and sincere in their approach. [/hider]
The environment in the realm can be extremely different everywhere. Somewhere in the realm is the portal back to the physical plane, where everyone needs to get. I think It would be a cool enough plot since anything can happen basically. I don't know if people would be willing to do this or not though so I'm posting it here.
Also you can be any character from tv show, movie, game, comic etc.
